IS LITECOIN A GOOD INVESTMENT? WHY HATERS MAY BE WRONG ABOUT THE CONTROVERSIAL CRYPTOCURRENCY
"THE BITCOIN BLOCKCHAIN IS CONGESTED."

— Litecoin founder Charlie Lee

USHERED INTO EXISTENCE BY GOOGLE ENGINEER CHARLIE LEE ON OCTOBER 13, 2011, LITECOIN IS THE 10TH LARGEST CRYPTOCURRENCY BY MARKET CAPITALIZATION TODAY.


Litecoin coin is an "OG" crypto. Aside from Bitcoin, no other coin has stayed in the top ten longer. BTC and LTC have held places in the charts for 410 and 409 weeks, respectively (other top performers include XRP at 396 weeks and ETH at 291).

It was created following a source code "fork" of the Bitcoin Core blockchain (a fork is when a blockchain diverges into two separate paths, creating two distinct coins). Litecoin’s biggest differences from Bitcoin include:

Lower transaction fees
A different hashing algorithm
A decreased block generation time
An increased maximum cap of coins
Don’t be deterred! We'll get into the specifics of these differences below and also have a look at how these factors contributed to Litecoin's success as a more "spendable" cryptocurrency. You may have heard Bitcoin described as “digital gold,” and following that line of thinking, Litecoin could be considered “digital silver.” But the cryptocurrency’s history isn’t as spotless as you might think.


In an April 26 interview with CNBC’s Worldwide Exchange, Lee discussed Litecoin, comparing and contrasting its attributes with those of Bitcoin. Although Lee is something of a polarizing entity in the cryptosphere, it’s worth hearing what he has to say about the cryptocurrency he invented. Let’s dive in.

Ethereum is up more than 50% in the past week. In 2021, the world’s second largest cryptocurrency has risen more than 360%. And since the stock market bottomed late last March, Ethereum is up an astonishing 2,200%.

During the 2017 crypto boom, Ethereum shot up to more than $1,400. After falling more than 90% during the eventual bust, it just surpassed that level in January of this year. Now it’s worth more than $3,200 as of this writing.

Bitcoin is performing well this year but it’s up “only” 100%. So why is ETH up so much more than Satoshi’s invention of late?


You can never drill these types of price moves down to a singular reason, so let’s look at what Ethereum is and does to get a better sense of the euphoria in this digital asset.

Back in the 2017 crypto bubble there were no use cases beyond using it as a store of value on the security of the blockchain. Now, there’s nothing wrong with a store of value as the main selling point for something like Bitcoin. Bitcoin has the potential to become the digital version of gold, which has itself been a store of value for thousands of years. And gold has an estimated market value of around $10 trillion.

Ethereum is more than a store of value. The bull market in 2017 was all about the possibilities of this technology, but there were no

Though digital coins and blockchain technology are relatively new, they are still prone to the same old types of scams that have been around for years. One of these scams is the pump and dump schemes.

Pump and dump schemes are illegal on regulated crypto exchanges. However, the unregulated crypto field has provided a rich ground for the schemes because users are sure they will not be easily caught by authorities.

For some in the blockchain niche, the main question is: “How do pump and dump schemes take place?” This post takes a closer look at the schemes to determine the process used to run them.

What Exactly is Pump and Dump?
Cryptocurrency pump and dump schemes represent a situation where an individual or group of persons plans to make a profit by pumping an asset into the market. The term “pumping” is used to indicate the purchasing of large quantities of coins to push the demand and price of respective coin up.

Then, they release the assets at a higher price to rake in a high return on investment. The scammers take advantage of the market dynamics of supply and demand to make investors see the price movements as a normal trend.

In many cases, scammers target new and unpopular coins that do not require a lot of money to manipulate. For example, scammers would rarely think of Bitcoin pump and dump to provoke a Bullish run because it would require a lot of money.

To rake in more from pump and dump schemes, scammers also target initial coin offerings (ICOs) because many investors are psychologically prepared to make a purchase. The ICO is preceded by intensive lobbying that target to showcase the pumped asset in good light.

How Dump and Pump Works
At the center of pump and dump schemes is a team of tech-abled, motivated, and organized players. These players operate from different points to make the publicity look genuine.

The team often includes investors who provide funding to buy the tokens and raise the demand. If the token selected is a low volume type asset, buying most of them allows scammers to control the supply and regulate the price.

As the inner team focuses on creating artificial supply, another team is working hard to demonstrate the good side of the tokens. In the past, scammers would use word of mouth to encourage people to buy dump and pump shares.

Today, scammers find it easy to motivate crypto buyers by using social media platforms such as Telegram, Facebook, and Twitter. Scammers even form groups and use influencer marketers to spread the ‘good’ word about the tokens.

Investors and traders rush to buy the tokens in fear of missing out at a high price. Once the scammers finally sell all their tokens, the hype and demand fizzles. The price suddenly crashes as investors realize it was a scam. But it is already too late!

The following figure demonstrates how a typical pump and dump looks.

XRP Price has pumped over 70% in the last hour, taking its price from $0.28 to near $0.5 mark for the first time since the SEC filed a lawsuit against Ripple. The price rise is suspected to be a pump driven by a Telegram group, helping the altcoin to finally overcome the $0.30 price barrier.

This is crazy even for crypto!

Is this Rise in XRP price a Pump-Dump?
Many in the crypto-verse raised suspicion about possible news with no other reason in sight for the pump.  TRON (TRX) rose quite similar to XRP yesterday owing to the similar pump owing to another Telegram group.

The frenzy about pumping small stocks began with GameStop when a Reddit group shot squeezed the GME stock to rise above $450.

Justin Sun, the founder of the Tron group took to Twitter to announce that he would buy 1 million GME stock followed by a pump in TRX price. Later it was revealed that thr pump was artificially created by a Telegram group probably trying to emulate the wallstreetbets, the Reddit group behind GME stock pump.

TRX rose over 42% during the pump before losing nearly all its gains within an hour of the rise. Many warned people to not rush into buying XRP looking at the price while XRP fans called it a natural pump owing to Ripple’s official rebuttal to the SEC lawsuit in a court filing.

Today, we filed our preliminary legal response to the SEC’s complaint. With it, we start to set the record straight and correct many misconceptions and contradictions within their allegations. 1/5 https://t.co/8KVBuSzCGH

— Stuart Alderoty (@s_alderoty) January 29, 2021

The short squeeze trend is now being used by Telegram groups to pump the price followed by a dump. This, many have warned against investing in such crypto assets that are being pumped artificially.

Though many known traders are defending the XRP price rise, the crypto community seems to be divided into two groups. Many known crypto traders are defending the XRP price as much awaited jump rather than a planned pump.

Regarding this $XRP “pump” group. They will always find a “narrative” to justify price movements. Ignore the fact that the chart has been absolutely primed for a big move that I’ve been tweeting about the past few days. https://t.co/8DWdVtUDuC

Crypto Wallets / Best Bitcoin Wallets
« on: May 07, 2021, 08:43:06 AM »


While the concept of Bitcoin may be new to some, this well-known cryptocurrency has been around for more than a decade. Bitcoin (BTC) is one of many digital currencies that have become fairly common investment holdings among tech-savvy households.

Proponents of cryptocurrencies argue that digital currencies are easier and safer, and come with better privacy, than traditional currencies. Because of its limited supply, Bitcoin has shown up on some people’s radar as an investment opportunity as well. Even the widely used PayPal mobile app is offering an option to buy, sell, and hold cryptocurrencies in its wallet. However, it should be noted that cryptocurrencies are still risky investments.

In short, a Bitcoin wallet stores a collection of bitcoin private keys. Typically, the wallet is password- or otherwise protected from unauthorized access. A Bitcoin wallet is controlled solely by its owner, not distributed and shared like blockchain technology.

Best Bitcoin Wallets of 2021
Best Overall: Coinbase
Best for Hardware Wallet for Security: Trezor
Best Hardware Wallet for Durability: Ledger
Best for Beginners: SoFi
Best for Free Buying and Selling: Robinhood
Best for Mobile: Mycelium
Best for Desktop: Exodus

Dogecoin Forum / Will Dogecoin Ever Reach $100?
« on: May 06, 2021, 12:49:03 PM »



There’s a high probability that Dogecoin will reach $1 per coin. $10 per Dogecoin is also likely within this decade. However, it’s impossible that Dogecoin will ever get to $100 per coin. Let’s explain.


Unlike other cryptocurrencies, Dogecoin doesn’t have a cap. In order to keep the network secure and operational, there’s always an incentive of 5 billion coins per year for miners. By the end of 2030, there will be 180 billion Dogecoin in circulation. If Dogecoin reaches $1 valuation per token, the total market cap of Doge would be $180 billion. It’s not that crazy high.

There are currently around 18 million Bitcoins in circulation, and it has a market cap of about $900 billion. The second-largest crypto Ethereum has a market cap of $200 billion. Similar to Dogecoin, Ethereum also doesn’t have a coin cap.

Over the years, Bitcoin and Ethereum have shown its strength and weaknesses.



Nowadays, Bitcoin is considered as an asset, an investment vehicle to grow money. Therefore, people now buy Bitcoin and hold on to it.

The transaction cost of Bitcoin is rising steadily. It’s already prohibitively high enough to be useful for daily retail transactions. Ethereum’s transaction fees are also high.

On the other hand, Dogecoin has promisingly low transaction fees. Moreover, as there are 5 billion coins per year for miners, the Dogecoin transfer fee will remain low. Furthermore, Dogecoin transfer time is 10x faster than Bitcoin.



So, there’s the tremendous growth potential for this coin. A market cap of $180 billion is not impossible. Therefore, $1 per Dogecoin is not a pipe dream. However, $100 per Dogecoin is quite unachievable. Let’s explain.

The US has a GDP of around $21 trillion, and China has approximately $15 trillion. If we sum up all the countries’ GDP, the total GDP would be $87 trillion.

Source: https://www.statista.com/statistics/268750/global-gross-domestic-product-gdp/



For each dollar increase in Dogecoin price, the market cap would need to rise $180 billion. So, for $100 per Dogecoin, the total market cap of Doge would be more than $18 trillion, greater than China’s economy and almost equal to the US economy. It’s absurd.



Many people don’t trust the US government. As treasury printing money, the government adding debt recklessly, and inflation soaring, many are dissatisfied. They want a financial system that is independent of any government control. That’s why over the years, Bitcoin and other cryptocurrencies became popular.

Still, the regular currency has superior use cases and functionality than cryptocurrency. Wider acceptance, faster and easier transfer are a few of them. Our whole economy revolves around traditional money. On the contrary, cryptocurrency is still in its infancy. Only a few people know about it, and it isn’t widely accepted. Cryptocurrency is also highly volatile.

Nevertheless, Bitcoin, Ethereum, and other cryptocurrencies have shown great potential. But still, it’s not enough to replace the US dollar.

There are hundreds of cryptocurrency. Every coin has pros and cons. Therefore, it’s tough to predict which one will become mainstream cryptocurrency. Even if single crypto becomes the world’s de facto crypto still, there’s no possibility that Dogecoin will ever become more valuable than China’s whole GDP. It doesn’t make any sense.



Therefore, Dogecoin will never reach $100 per coin. However, from our experience with Bitcoin and Ethereum, we expect that Dogecoin will reach $1 because it has far more potential than Bitcoin. Even Tesla and SpaceX CEO Elon Musk believes that Dogecoin is underestimated. Elon Musk is the founder of X.com, which later became PayPal. Therefore, he knows what he is talking about.

The Litecoin price is attempting to bounce back after dropping to a multi-week low of $170 yesterday. The LTC is trading at $192, which is 6.7% above its lowest level this week. Its market cap is at$12.89 billion, according to data compiled by Coin Marketcap.

What happened: Litecoin has been an embattled cryptocurrency after it reached an all-time high of $245. It has dropped by more than 22% from this high. This performance is mostly because of the overall weakness of cryptocurrencies, especially Bitcoin.

As one of the oldest digital currencies in the world, Litecoin tends to track the performance of Bitcoin. That’s because many traders see it as a relatively cheaper alternative to BTC, which is trading close to $60,000.

Recently, demand for Litecoin has been relatively weak. In fact, a quick look at social media mentions and Google search trends show that fewer people are searching for the currency.


Litecoin price forecast
The four-hour chart shows that the LTC price dropped to $152 during the February crypto sell-off. This was a 38% below its all-time high. Since then, the digital currency rebounded and rose to a high of $230, which was slightly below where it was in February.

A closer look at the chart also shows that it has formed what seems like a head and shoulders pattern, with the month-to-date high being the head. Therefore, the Litecoin price may resume the downward trend and possibly retest the February low of $152. This is a 20% drop below the current level. On the flip side, a move above the right shoulder at $200 will invalidate this trend.

Ethereum is the major blockchain when it comes to tokens, tokenization, and also DeFi projects. However, the increase in popularity comes with its costs. The more users and projects are relying on Ethereum, the scarcer the resources. Ethereum is still very limited to transactions per second. No more than about 12 transactions per second. These 12 transactions are distributed between all entities globally.

To visual that, let’s take a view of the average fee per transaction over the last five years:


source: https://blockchair.com/ethereum/charts/average-transaction-fee-usd
You can clearly see the three spikes. The first one occurred in late 2017 with the success of ICO. Initial Coin Offerings was (and still is) the activity to issue newly created tokens on Ethereum and to sell them to the community. Ideally, this sparks the project behind the tokens to be successful. Hundreds of ICO were done in summer 2017 – per week.

The second spike was shortly after in summer 2018 with the launch of Cryptokitties. The card game was revolutionary. It allows players to create, trade, and collect cards with different kitties and every one with its own design and attributes. Every trade was reflected in Ethereum. Well, it’s kind of obvious that if several thousand players try to trade cards on an infrastructure that it is only able to manage about 12 transactions per second – globally. As the hype around Cryptokitties declined, the fees decreased as well.

The third, and current spike in late 2020, is rooted in the rise of DeFi. Decentralized Finance promises to enable people to take their finance into their hands without any middleman. Staking and lending are some of the buzzwords.

As long as Ethereum has such limitations, spikes like the past three will occur again. This might change with the upgrade to Ethereum 2.0 which aims to manage several thousand transactions per second.

However, it’s fully unclear when this upgrade will be released. We at Tangany don’t expect to see full 2.0 before 2023. This is why we, together with our partners, have identified alternatives to reduce network fees.

Action   Complexity   Time for implementation   Effect (at reducing network fees)   How much of the work can be covered by Tangany?
Omnibus Wallet Architecture   high   1 - 2 months   high   75% (mostly covered by Tangany)
Migration to another blockchain   medium to high   0 - 2 months   medium to high   100% (Binance Smart Chain is already usable, EOS and Tezos are prepared)
Efficient Smart Contracts   medium   1 - 2 weeks   low to medium   25% (Tangany can only consult on that)
Optimized Gas Estimation   low   1 - 2 days   medium   100% (built-in solution)
Second-layer Solution   medium   medium   high   100% (built-in solution)
Omnibus Wallet Architecture
It’s common best practice to use one wallet per user. For one, this reflects the original idea of blockchain the best and secondly, there are (nearly) unlimited numbers of wallets available.

This is also the approach we and our partners see with most. Exceptions are exchanges (for the same reasons) that are using the omnibus wallet since the beginning.

An omnibus wallet architecture means that instead of using one wallet per user, to switch to a centralized form. Only one or a couple of wallets are being used for all users. With that, transactions are no longer done on-chain but off-chain. If an asset is to be allocated to another user, this record will not be on the blockchain. Therefore, zero transaction fees.

The tricky part is to have a powerful off-chain ledger in place. And with that, we don’t mean a .csv file. This ledger could be something like a private blockchain (we generally recommend Quorum for that purpose). On this private blockchain, every user will have it’s own wallet again. These wallets will mirror all the assets. It’s some kind of customized second-layer solution for Ethereum.

So, if a user wants to know his balance in the omnibus wallet, we only have to take a look at his non-disclosed private blockchain wallet. So if a transaction should be done it will only be executed on the private blockchain.

As the private blockchain comes with zero transaction fees and higher scalability, there are no restrictions. It is even possible to implement an explorer for transparency reasons if required.

That leads to reduced transaction fees of 100%. Such an architecture can also be used for other blockchains like Bitcoin, Tezos, or EOS.

From a legal point of view, this is doable within the European Union as it was validated by Tangany. This includes cryptocurrencies, stable coins, and security tokens.

Ethereum Second-Layer Solutions
In the past few months, a few second-layer solutions have emerged. Those solutions are way more matured now compared to a couple of years before. Namely Polygon (formerly known as Matic) is a highly demanded solution to overcome the limitation of Ethereum. Polygon is 100% compatible with Ethereum and enables to send assets back and forth between those two blockchains.

Polygon can also be used via the Tangany API and enables the functionality to migrate back to Ethereum once the scaling issues are settled which should be the case with the Ethereum 2.0 phase 1 upgrade.

In our view at Tangany, this seems to be a quite simple but efficient method to save on the network fees. If you would like to learn more visit https://tangany.com.

Migration to another blockchain
Depending on the business case, migration to another blockchain could be reasonable. If the project hasn’t officially started yet even better.

No matter if migrated or directly started on another blockchain, leaving Ethereum comes with its pros and cons. The pros are often higher scalability and with that way lower transaction fees. We are speaking here up to 99% lower.

However, we have to consider also the cons. The most important one is for sure that Ethereum is some kind of market leader for tokens. Leaving the platform might make it harder to get the token supported on 3rd party services like exchanges. Additionally, Ethereum is quite well-known, tested and validated for 5 years.

Similar alternatives to Ethereum are EOS, Binance Smart Chain and Tezos. Those three blockchains support smart contracts, have often a similar technical architecture and are also considered to be reliable. At Binance and Tezos it’s even possible to re-use the same wallets as on Ethereum.

The migration can be done quite easily. All tokens need to be redeployed on the new blockchain. If the same wallet can be used, the tokens will be distributed automatically. If a new wallet is required (because the blockchain uses another cryptography), those are generated first before the tokens are distributed accordingly.

Efficient Smart Contracts
Another, less radical approach compared to the ones before, is to optimize the smart contract. The higher the complexity of the smart contract, the higher the fees. That is why a smart contract should be as simple and small as possible. Remove all unneeded functions and check if the code can be simplified. Maybe even validate whether some functions could be done outside of the smart contract such as the management of a whitelist.

With that we have seen decreased network fees by 33%.

Optimized Gas Estimation
For every transaction, there is the possibility to set the amount of fee. Depending on the urgency of the transaction, the included fee can be reduced. The less fee is included, the longer it takes until the transaction is executed.

As the fee level is very volatile it is recommended to recheck the current market price for transactions. By not using outdated market prices it is possible to save about 25% of the fees per transaction.

Another benefit by using the latest market price is that transactions can be timed. This means, the approximately time until the transaction is executed can be estimated. By using a Gas fee which is 25% below the market price, it will take slightly longer. By 25% above it will be faster.

That optimization can easily be done with Tangany Custody Suite and our powerful API which comes with an in-built solution for that.

Conclusion
No matter what activities are done on Ethereum, the limitation of scalability will still be part of that for quite some years. Avoiding high Ethereum transaction fees is always a good project to tackle.

Tangany has accumulated a lot of experience with that in the past years and our API is able to provide out-of-the-box solutions in most cases.

In November 2011, Wired magazine ran an article titled “The Rise and Fall of Bitcoin.” The article delivered a narrative account of the digital currency and its pseudonymous founder Satoshi Nakamoto. The story was written as if it encapsulated the full story of Bitcoin, from its 2008 rise to its probable 2011 demise. Four years later, the suggestion that Bitcoin had run its full course by 2011 sounds comical.

Although Bitcoin supposedly fell five years ago, the media seems not to have noticed. Since its release, Bitcoin has “died” a total of 78 times, with major news outlets continuing to announce the death of Bitcoin all the way through 2013, 2014, and 2015. Bitcoin did not die in 2011, and it is not dead today. Nevertheless, the fledgling currency has failed to thrive to the degree that many had hoped it would. Most Americans remained unfamiliar with Bitcoin in 2015, and Bitcoin adoption rates remain slow among merchants and consumers.

There are numerous obstacles to Bitcoin’s adoption as a legitimate currency—from security issues and low incentives for use to high volatility and a reputation as the currency of criminality—but a number of startups have emerged to combat these obstacles through the development of much-needed infrastructure.

A Decentralized Virtual Currency

A virtual currency does not exist in any physical form. While the U.S. dollar is represented by physical coins and paper, bitcoins are represented virtually by unique strings of characters. Every fraction of a bitcoin has an identifier that, like funds on a credit card, can be sent and received over the Internet to make transactions. Microsoft Points, Amazon Points, and World of Warcraft Gold are all familiar examples of virtual currency.

Although virtual currencies are nothing new, Bitcoin is unique because it is a decentralized virtual currency that uses cryptography and a distributed ledger called a blockchain “to control its creation, administration and security.” Unlike traditional, fiat currencies, Bitcoin is not tied to any specific government or entity. As a result, transactions can be difficult to trace, occur faster than transactions that need to be processed by banks, and cannot be blocked. Bitcoin is not the only currency of it’s kind–similar alternatives include Dogecoin and Litecoin–but it is by far the most popular.

The Security Challenge

The first barrier to widespread Bitcoin adoption is security. Although the difficulty to trace bitcoins forms part of the currency’s popularity among current users, critics see this as a security concern, since pseudo-anonymity makes it hard to identify fraudsters. Furthermore, Bitcoin relies on the adoption of digital “wallets” for storing bitcoins and making transactions, but these wallets must be secure in order for people to start using them. Although reputable companies like Apple, Samsung, and Google have all released digital wallets for making transactions with traditional currencies, a July 2015 Gallup survey suggests only 2% of smartphone users actually use these products, with a majority (55%) of non-users citing security concerns as their primary deterrent.

The lack of oversight by a central party means that trustworthy infrastructure is hard to find, and fraud can be as simple as stealing a unique Bitcoin key like one would steal a dollar bill. This lack of security was on display in 2014 when Mt. Gox, the most popular Bitcoin exchange, closed its doors after 800,000 of its customers’ bitcoins (worth around $460 million at the time) went missing. Mt. Gox claimed the bitcoins were stolen by hackers, but they later recovered 200,000 bitcoins from their own overlooked servers. Furthermore, in 2015, Mt. Gox’s own CEO was charged with the unrelated theft of $2.7 million worth of his customers’ bitcoins. Although it appears most of the still-missing bitcoins were indeed stolen by hackers, the primary blame for the theft has been placed on vulnerabilities stemming from Mt. Gox’s own gross mismanagement rather than any vulnerabilities of Bitcoin. Whether or not Bitcoin itself is insecure, the Mt. Gox debacle illustrates some of the problems that can arise when a currency lacks mature infrastructure and centralized security and regulation.

One company, Coinalytics, has taken a back-end-focused approach to security that aims to help future companies avoid facing security problems like those faced by Mt. Gox. Coinalytics co-founder and CEO Fabio Federici explained to the HPR how his company enhances Bitcoin security by “helping companies with compliance, and assessing who they are transacting with and where their transactions are coming from.”

Ken Miller, former COO of the Blockchain technology firm Gem, told the HPR that “in order for [Bitcoin] to take off, you need people to feel as comfortable or more comfortable than they are used to.” As such, Miller explained how Gem worked for the better part of a year to develop a Bitcoin wallet with “enterprise level, better-than-your-bank-type security.”

People need to be persuaded not only to trust Bitcoin, but to trust the exchanges, digital wallets, and other services that are vital to their use.

TRON (TRX) Forum + Ecosystem / What Is Tron?
« on: May 06, 2021, 12:30:16 PM »



Tron is a blockchain-based decentralized platform that aims to build a free, global digital content entertainment system with distributed storage technology, and allows easy and cost-effective sharing of digital content.

Tron was founded in September 2017 by a Singapore based non-profit organization called the Tron Foundation. It is headed by CEO Justin Sun and has a dedicated in-house #DevelopmentTeam  that includes renowned technology stalwarts. This article explores the Tron network, its workings, and its cryptocurrency Tronix (TRX).1


Eliminate the Middle Man
By using the features of the blockchain and peer-to-peer (P2P) network technology, Tron attempts to bridge the gap between content creators and content consumers by eliminating the middleman. The result is an overall cost reduction for the consumer and improved collection through direct receipts for the content producer, which offers a win-win situation.

To draw an analogy with a real-world application, consider Netflix, which operates a digital entertainment service offering on-demand content. A single organization controls the services in a centralized manner. One may need to subscribe and pay Netflix to watch a particular on-demand movie that may have been produced by a group of budding enthusiasts who are hosting it on the Netflix platform. From the fee charged to the subscriber, Netflix takes a cut for hosting the movie on its platform and pays the remainder to producers. Often, the lion’s share is taken by the middleman.


Tron replicates this business model on a public blockchain network and acts as a distributed, decentralized storage facility that makes it more efficient and cost-effective. It aims to eliminate the middleman, like Netflix in the above example, by allowing anyone and everyone to host digital entertainment content on its blockchain-based network. The global audience can directly pay the content creators to access the content.

In the process, Tron's open,

Cryptocurrency has been all around the world these days. People want to know and want to enter this fruitful world to achieve. The feasibility of gaining success by sitting g at home has made people more curious about it.

People can easily earn a handful of amounts by trading, investing, and holding cryptocurrencies for a long period. Thousands of them have started staking cryptocurrencies through the platforms such as Bitcoin Loophole trading platform and came to know that they can make money out of leveraging staking validators or wallets.

Earlier to make money a trader and investor were required to either trade or invest by buying and selling the coins. This was done with great care and by learning all the technical education. However, the recent situation has made people find ways to earn, and staking is one of them.

During these years the investment vehicles have allowed crypto assets holders to, make money out of these avenues. Let's delve deeper and look into this guide.

What is Cryptocurrency staking?

Despite the sudden declines and sudden rises, people had found the staking is a way of generating a passive income for holders of coins. This scheme was first introduced in 2012. Sunny King and Scott Nadal introduced the peer to peer cryptocurrency, Peercoin. It was the reward for the proof of stake consensus algorithm. Since then many other cryptocurrencies have implemented this stake algorithm into their systems.

This term staking might puzzle you but basically, it is an algorithm. In other words, a consensus algorithm. New blocks are created and added to the blockchain in this type of algorithm. The newly created blocks are then staked by the person who already possesses some coins.

Incorporated exchange: Yes
Exodus is a desktop and mobile wallet with a very simple user interface and an exchange built-in. One of Exodus’s most popular features is the ability to swap between a growing number of cryptocurrencies. Exodus currently allows for swaps between over 100 different cryptocurrencies.

With its simplicity, this wallet is great for beginners just getting into the crypto space. It also has great support, which is an essential feature for beginners getting into what many would consider a confusing market.

While it is great for beginners, more advanced users may find it lacking in some features. First, Exodus is a closed source wallet. This goes against the ethos of the idea of Bitcoin and blockchain and can create some security concerns as its code is not open for everyone to see. Instead, users rely on the Exodus team to ensure there are no holes in the security of its wallet.

আমরা যারা নতুন রয়েছি এই ফোরামে তারা অনেকেই জানেন না যে বিনিয়োগ কি বা ট্রেড কি।
আমি আজ তাদের জন্য এই বিষয়ে কিছু তথ্য তুলে ধরার চেষ্টা করবো।
ট্রেড কিঃ আমরা বাংলাদেশের সকল মানুষ ব্যবসা সম্পর্কে ভালো জানি। আর ট্রেড হলো ব্যবসা বা বানিজ্য।  আপনি যদি ব্যবসা করেন তাহলে আপনাকে কিছু পন্য নিয়ে শুরু করতে হবে। যেমন আপনি কাপড়ের, কাচামাল,স্টিল,সিরামিকের ব্যবসা শুরু করলেন। এর জন্য আপনাকে অবশ্যই একটি শপ নিতে হবে। এবং আপনার পন্যগুলো ক্রয় এবং বিক্রয় করতে হবে। আর আপনি যদি ব্যবসাতে কম দামে পন্য কিনে বেশী দামে পন্য বিক্রি করেন তাহলেই কিন্তু আপনি লাভবান হবেন। আর ঠিক এভাবেই আমরা ক্রিপটো বিশ্বে ট্রেড করবো। ক্রিপটো বিশ্বে ট্রেড করার জন্য আমাদের ভালো একচেন্জ সাইট বেছে নিতে হবে। আপনি বিন্যান্স, কুকয়েন,এফটিএক্স একচেন্জ সাইট বেছে নিতে পারেন।এগুলো একচেন্জ সাইট খুব নিরাপদ।  এই সাইটে আপনি ভালো মুদ্রা দিয়ে ট্রেড শুরু করতে পারেন। ধরনে বিএনবি কয়েন এর দাম কমে গেলো তখন আপনি কিনে নিলেন আবার দেখলেন এর দাম বেড়ে গেলো তখন আপনি তা বিক্রি করে দিলেন। আর এভাবে আপনি লাভবান হলেন। তবে ক্রিপটো বিশ্বে ট্রেড করার জন্য আপনাকে অবশ্যই অভিজ্ঞতা লাভ করতে হবে। কারন ক্রিপটো বিশ্বে আপনি অনেক ভ্যালুহীন কয়েন পাবেন,আর আপনি যদি ভ্যালুহীন কয়েন কিনেন তাহলে কিন্তু আপনি ক্ষতিগ্রস্ত হবেন।
আবার অনেকেই বলেন যে ট্রেড কি শর্ট টাইম করবো নাকি লং টাইম করবো। আমি তাদের বলবো, আপনার অভিজ্ঞতা অনুসারে সেটি নির্ভর করবে। আপনি যদি কয়েন এর বাজার অনুমান ও টেকনিক্যাল এনালাইসিস করতে জানেন তাহলে আপনি খুব সহজেই বুঝে নিবেন কত টাইমের জন্য ট্রেড করলে ভালো হয়। তবে আমি আপনাদের বলবো কয়েন এর বাজার দেখবেন এবং আপনার যদি প্রফিট হয়ে থাকে তাহলে আপনি কয়েন বিক্রি করে দিবেন। আপনি যদি বেশী লোভ করেন তাহলে ধরে রাখেন আপনি ক্ষতিগ্রস্ত হবেন। কারন ক্রিপটো মুদ্রা সবসময় অস্থির থাকে। বেশী পাম্প হলে কয়েন অবশ্যই ডাম্প করে। তাই ট্রেড করার সময় লোভী হওয়া যাবেনা। আপনাকে ধৈর্য ধারন করতে হবে। আপনার আবেগ নিয়ন্ত্রণ করতে হবে। ধরেন আপনি কয়েন কিনলেন তারপর এর দাম ডাম্প করলো বা কমে গেলো,তখন আপনি যদি ভীত হয়ে পড়েন বা আবেগ নিয়ন্ত্রণ না করে কয়েন বিক্রি করে দেন তাহলে কিন্তু আপনি ক্ষতিগ্রস্ত হবেন।

বিনিয়োগ কিঃ বিনিয়োগ বলতে আমরা লম্বা ভ্রমনকে বুঝিয়ে থাকি। সহজ ভাষায় আপনি যদি কক্সবাজার ঘুরতে যান আর যদি অল্প সময় ঘুরে চলে আসেন তাহলে আপনি ততটা আনন্দ করতে পারবেন না,আর আপনি যদি সময় নিয়ে যান তাহলে আপনি সবকিছু ভালো করে ঘুরতে পারবেন। এর ফলে আপনি পরিপূর্ণ আনন্দ পাবেন। তাই বিনিয়োগ কোনো এককালীন ইভেন্ট নয় এই কথা সবাইকে মাথায় রাখতে হবে।
ক্রিপটো বিশ্বে বিনিয়োগ করার জন্য আমাদের অবশ্যই অভিজ্ঞতা অর্জন করার দরকার রয়েছে। আপনি যদি অভিজ্ঞতা ছাড়াই বিনিয়োগ করেন তাহলে ক্ষতিগ্রস্ত হবেন। বিনিয়োগের জন্য আপনাকে সেরা ও জনপ্রিয় কয়েনগুলো বেছে নিতে হবে। আপনি যদি ভ্যালুহীন কয়েন কিনে ফেলেন তাহলে কিন্তু কতটা লস খাবেন তা বলার অপেক্ষা রাখেনা। কিছু একচেন্জ সাইট রয়েছে যেখানে আপনি কোনো কয়েন বা টোকেন দিয়ে বিনিয়োগ করলে প্রতিদিন বা সপ্তাহে কিছু লাভ পাবেন। যেমন yobit সাইটে বিনিয়োগ করতে পারেন,তবে আমি এই সাইটে বিনিয়োগ করার জন্য ততটা পরামর্শ দিবোনা। কারন সেখানে তাদের অনেক শিটকয়েন থাকে এবং কিছুদিনের মধ্যে সে কয়েনগুলোর দাম ভ্যালুহীন করে ফেলে। তবে বিনিয়োগ করার জন্য আপনারা সবসময় মাল্টিপল কয়েন বেছে নিবেন এর ফলে একটি কয়েনে লস হলে আরেক কয়েনে লাভ হবে। এর ফলে আপনি ঝুকিমুক্ত থাকবেন। আমরা আরেককথায় হোল্ড কেও বিনিয়োগ বলতে পারি। আমরা আমাদের প্রাইভেট ওয়ালেটে কয়েকটি মুদ্রা কিনে রেখে দিবো দীর্ঘদিনের জন্য এর ফলে আমরা একসময় উচ্চ রির্টান পাবো। আমি বিনিয়োগ করার জন্য কিছু কয়েন সাজেস্ট করবো। এলটিসি,ডট,কারডানো,এক্সআরপি,ডোজ,ইউনিসোয়াপ,এক্সএলএম। আর আপনারা আমার কথা মতো বিনিয়োগ করলেন তা কিন্তু হবেনা। অবশ্যই আপনাকে রিসার্চ করতে হবে। কারন কারো কথামতো কোনো কাজ করবেন না। ক্রিপটো বিশ্বে কাউকে কখনো অন্ধ বিশ্বাস করবেন না। প্রথমে নিজে গবেষনা করবেন এবং না বুঝলে কারো থেকে সাহায্য নিবেন।

যদি কেউ কিছু না বুঝে থাকেন তাহলে জানাবেন।
ধন্যবাদ সবাইকে😍
আমি আপনাকে অনেক অনেক ধন্যবাদ জানাই আপনার সবগুলাই পোস্ট আমি কমপক্ষে দুইবার করে পরি তার কারণ আপনার পোস্টগুলো পড়ে অনেক কিছু শিখতে পারি আশা করি এরপরে আরো অজানা তথ্যগুলো আমাদের মাঝে শেয়ার করবেন ধন্যবাদ আপনাকে
