Anyone here using their services?

We've seen in the news in the past few days that one was shutdown by the Europol (BestMixer). I just read, in a different forum, that another one (Bitblender) has decided to stop their services as well. Although no official reason has been given yet.

Coingecko has introduced its Trust Score recently to fight fake exchange volumes. I think this is a much needed change since many are still relying on volume when choosing an exchange to trade but are unaware that those volume are manipulated.

I noticed that some users, reported for plagiarism and punished with multiple negative karma, have joined a new bounty campaign (signature). I have not checked the ZROCOR bounty thread yet but if you are a legit participant in their signature campaign, I suggest you ask the bounty manager if they'll allow accounts -karma.

The European cryptocurrency exchange that claims over 775,000 customers has recently announced Dash integration for crypto-to-cypto trading.

Crypto-to-crypto trading means that coins are sent directly between users’ wallets and “are not deposited on the wallets of Bitcoin.de, but sent from the private wallet of the seller directly to the private wallet of the buyer. Instead, “Bitcoin.de manages only the Bitcoins, which serve as means of payment for the purchase of the other crypto currencies”. Previously, they offered a similar system with euros since bitcoin.de would hold the “seller’s bitcoins in trust, the euro involved in the deal is transferred directly from the buyer’s bank account to that of the seller”, and then “once the euro transaction is confirmed, Bitcoin.de releases the reserved bitcoins to the buyer”. With crypto-to-crypto trading, the method will be the same, but Dash will be taking the place of the euro.

Bitcoin.de highlights a major advantage of this system is that it vastly increases the speed of trading.

Quote
“An advantage of this model is that customers can react faster. With conventional stock exchanges it is necessary to deposit cryptocurrencies first on a Wallet of the stock exchange operator, which can take 10 minutes up to possibly several hours. With crypto-to-crypto trading, customers can accept an offer as soon as they have access to their cryptocurrency.”

Bitcoin.de only charges a 0.5% fee for the trading transaction, which is pretty cheap by market standards.


Increasing Dash access and usage
This new integration further helps increase access to Dash in Europe since every exchange offers fiat-to-Bitcoin, but may not offer fiat-to-Dash. Now, consumers can easily purchase Bitcoin with fiat, trade into Dash on bitcoin.de, and then use their Dash to make purchases at merchants that accept Dash. Further, since bitcoin.de has such a large customer base in Europe, many who have not yet heard of Dash will be exposed to Dash. This helps spread adoption as consumers learn how much faster and cheaper Dash is, along with its optional PrivateSend feature and security features that make it attractive for everyday usage by consumers and merchants.

Additionally, since bitcoin.de is peer-to-peer with escrow of Bitcoin as payment, they are bridging the middle ground between centralized exchanges and pure P2P exchanges. Centralized exchanges can institute various rules and ban users from accessing their funds for failure to comply, which could technically still occur on bitcoin.de since a users’ Bitcoins are held in escrow for payment of other coins, but at least the coins they purchase are immediately transferred to their private wallets. Another advantage is mitigating the reliance of placing complete trust on the counterparty since users’ Bitcoins are not released until they confirm receipt of the coins they purchased. Bitcoin.de also mitigates trust risk by implementing their own rating system.

Bitcoin.de crypto-to-crypto exchange also teaches users how to be responsible for their own private keys, which is how cryptocurrencies were originally intended to be used. Whereas many crypto users currently just store all their money on exchanges where they do not own their private keys and thus their money. The fallout of this error is always seen when an exchange gets hacked and consumers lose very significant amounts of money.


Breaking the parallel movement with Bitcoin
The cryptocurrency market still suffers from the inability for coin prices to move independently of Bitcoin’s price; whenever Bitcoin is appreciating, most other coins are appreciating and whenever Bitcoin is depreciating, most other coins are depreciating. This is to be expected, to a degree, since the industry is still so young and most consumers only know and trade based on the brand name of Bitcoin. However, to become a mature market, coins have to start performing independently based on their own value offerings. Thus, by allowing consumers to directly trade Bitcoin for Dash, Bitcoin.de will inherently contribute to market performance independence since users will be decreasing (increasing) the demand (supply) of Bitcoin and increasing (decreasing) the demand (supply) of Dash.

As consumers further realize the advantages of Dash like automatic InstantSend, Deterministic Masternode Lists, PrivateSend, the coming ChainLocks release, and other features that make it more competitive for consumer and merchant use in everyday life, then they will be more inclined to treat its exchange price and performance differently.

Everyone in this space talks about how cryptocurrency has the potential to change the world. Key examples given are countries such as Venezuela with hyperinflation and broken payment systems, or the unbanked of Ghana, or politically targeted organizations like WikiLeaks. These reasons are often given as justification for using cryptocurrency, both to those groups represented in the examples, and to the average first-world person who shares none of the same concerns. The fact is, most of the developed world has no compelling reason to switch to using cryptocurrency as they’re mostly very satisfied with the payments systems they have right now. Thankfully, though, there is one way to get them to actually switch.


General benefits and niche industry use aren’t enough to make everyone else switch
One of the hardest sells I’ve attempted in recent times is to pitch cryptocurrency to businesses and users primarily for its hard and meSPAM BANble benefits. Lower fees, instant settlement, better security, no chargebacks, it doesn’t matter. Nearly everyone in the developed world gets paid easily and can spend their money everywhere without too much trouble. Businesses have it a little harder, bearing the brunt of the infrastructure costs and transaction fees, but even this is not significantly worse than what it would be like if they used cryptocurrency instead. Generally speaking there are still quite a few benefits, but they’re just too slim to make a compelling argument for users and businesses to switch.

Now, there are a few key industries where the spread is much thicker, such as the cannabis industry, online gambling, fitness supplements, cross-border remittances, and other areas where the hard advantages of using cryptocurrency may be enough to warrant a change. However, the general populace that doesn’t partake in these narrow economic corridors will not change their entire way they transact because of this. Even people who will, for example, buy their weed with Dash because they save money won’t also use it to pay their rent where they don’t stand to save.


No one needs to use crypto… but they want to
While trying to pitch cryptocurrency, I put aside my personal reasons for using it to focus on the more seemingly objective, rational, and mainstream-appealing benefits. Big mistake. It turns out that the “benefits talk” is nowhere near as exciting as the “cool talk”: it’s exciting and fun to use. In my case, it was exciting because of ideological reasons and because of the different and innovative nature of the underlying technology, and it was fun to send and receive digital tokens run by a decentralized infrastructure with ease and without restriction. More importantly, using cryptocurrency feels free, a stark contrast with the serious, over-regulated, highly-permissioned, and controlled financial world. Using crypto feels as effortless as sending a message or leaving an online comment. It doesn’t feel like money in that there isn’t that gravitas and stress associated with the typical financial experience.

In my experience, this intangible, loosely defined experiential benefit is what got people excited by crypto and wanting to switch. Sure, all the benefits of fee savings, instant settlement, no middlemen, etc. were important points, but they all fed into this general excitement to use something new and revolutionary, and not an excitement to save money and transact more efficiently.


Businesses switch to get ahead of the curve
Merchants, with their settlement time worries and several-percent transaction fees, stand to gain the most from using cryptocurrency. However, while businesses I talked to saw these as important elements, they didn’t really get their attention or push them any closer to accepting it for payments. What did, however, get them going was FOMO: fear of missing out. In the short term, merchants wanted to take crypto payments to attract new customers excited to be able to spend it, and in the long term to adopt a new payment technology generally regarded as the eventual “future” before being left behind by the times.

Notice that this is a hard value proposition based on a soft one: Get more customers now, lose fewer later, is a very hard and practical benefit for a business. The reason for the new customers, however, is the very soft “because they’re excited by it” reason.


Come for the fun, stay for the benefits
Now while all this fun and excitement is enough to get people to start using a new payment system, they won’t stay long-term unless it makes sense. If it remains cheap, easy, and frictionless to use, people who start using crypto, and can spend it on most things, will continue to do so. Particularly once a wave of businesses starts accepting it to attract a wave of newly-inspired users, the network effects should be strong enough that the advantages start to compound. At that point of critical mass, only a madman would turn back to the antiquated, struggling, centralized payment networks of yesteryear.

This is the decentralized digital currency revolution. Anyone can send value freely without using any other service or company, without restriction, without censorship, without control. Pure freedom. And using it feels like that: freedom, the way money is supposed to be. That’s worth getting excited about. Pass on the joy, it’s contagious. Just remember that the inherent benefits of the system will have to one day cash the check that the excitement writes.

Cryptocurrency discussions / What Is a Poison Block Attack?
« on: April 12, 2019, 08:28:35 PM »

In 2009 the world was introduced to its first Bitcoin node. Here node means a computer that runs special software that can service the Bitcoin network. Transactions are then put together into a block and released to the network. The block then needs to be disseminated to all nodes in the network. As there became more demand for Bitcoin transactions, a block might not reach every node as quickly as desired.


Compact and Xthin blocks to solve propagation, and their new considerations
The Bitcoin core developers had a fix for this situation. They called their solution compact blocks. The idea is simple. Instead of broadcasting every transaction in the block. Only broadcast a list of identifiers of the transactions. As almost all transactions are stored by every node, the receiving node can then find the transactions that are identified and construct the block. The block can then be securely verified as correct. If any transactions are missing then the node can request those transactions from connected nodes. Compact blocks saves bandwidth, but it introduces a possible new step. This new step of asking for missing transactions.

Asking for new transactions involves two way communication which will introduce latency. The Bitcoin Unlimited team had a plan to reduce the need to request missing transactions. If a node asked for a block, a bloom filter of all known transactions was sent with the request. This way the sending node could predict which transactions might be missing and send them along with the list of transaction identifiers. This was called Xtreme thinblocks or Xthin propagation.


The Poison block attack to slow down propagation
Both these protocols as well as the Graphene protocol discussed in a previous article rely on transactions being available by receiving nodes in order to successfully speed-up propagation. All these protocols will eventually fall back on block propagation with no speedup if the transactions are not available.

In fact a miner could choose to include transactions in a block which have not been broadcast to the network. Such a block is called a poison block. A poison block would render the propagation speedups ineffective. Further, a failed attempt at a quicker propagation will delay sharing useful information. The result of a poison block will be a network hiccup, some nodes could be a block ahead while other nodes catch up. There is also a greater chance that a poison block will be orphaned and ignored by the network.

A poison block can only be created by a miner. Incentives are such that a miner should not want to create a poison block. Networks are resilient enough to process poison blocks and go on.

Celsius, which currently has $50 million USD in assets under management, will now enable Dash users to deposit their money on the platform and earn interest and take out loans on their Dash with no minimum or maximum lockup.

Celsius is able to offer returns to users that range from 3% to 7.5%, with Dash currently being the highest, since they hold coins in wallets owned by “BitGo and lent out to hedge funds/exchanges/institutional traders”. However, they enhance solvency since “up to 150% of the value is provided in another collateral (typically USD)”, according to their FAQ page and an in-depth analysis by one of their members. Interest payments are calculated weekly Friday-Thursday and paid out, in the same cryptocurrency as what is deposited, on every Monday. However, the interest is not compounded since they “rather give consumers the highest rates possible” and “compounded interest is simply not a sustainable business model at this time”.

The platform does not have a minimum or maximum deposit, but does limit daily withdrawals to $20,000 USD per day. A user can withdrawal more, but must “email [email protected] and verify their identity” with KYC documents. As an additional security measure, they lock-in the first wallet that funds are sent to from the platform to prevent incentivizing hacking and changing destination addresses. Furthermore, since they use BitGo as a custodian, they benefit from BitGo’s $100 million USD insurance policy.


Borrowing using cryptocurrencies
Celsius also enables users to borrow money using cryptocurrencies, which is a step towards meshing the cryptocurrency world with the current model of finance. Borrowing via cryptocurrency also helps stabilize the cryptocurrency markets since crypto enthusiasts can get liquidity for their various projects without having to sell off massive amounts of funds. Celsius offers very competitive terms, even when compared to traditional banks, such as six or twelve month loans, no pre-payment penalties, and rates starting at 4.95%. The borrowing rate does depend on the loan-to-collateral value ratio, which is understandable considering the relatively high volatility of cryptocurrencies.

Nevertheless, Celsius stands out among other cryptocurrency lending and borrowing companies that often charge high rates and have onerous terms. This allows Celsius to pursue the original goals of cryptocurrency to introduce more consumer-friendly and accessible finance to more individuals. Celsius also plans to introduce their own token soon, which will give users better rates on the platform.


Dash completing the adoption loop
Many got into cryptocurrencies to escape the system of the traditional banking sector, but lending and borrowing is still part of a healthy economy when done properly. Thus, platforms such as SALT are starting to emerge that enable cryptocurrency to be used in the lending and borrowing process. This will further enable individuals in the Dash community to actively improve their well-being without selling off Dash during a market upturn, which will also help enhance stability. Now individuals can save their Dash to get returns, borrow against their Dash to pursue projects, merchants can accept Dash, and consumers can spend Dash that they have earned. As Dash continues to grow, it is growing as a complete environment that can be self-sustaining rather than only focusing on one area of growth.

Binance’s official digital currency wallet app Trust Wallet has added staking for cryptocurrencies. The development was announced by Binance in a blog post published on April 3.

The staking feature — which is scheduled to be launched by Binance by the end of the second quarter of 2019 — enables users to earn dividends or interest on their investment for validating transactions and allows them to vote on changes in the blockchain. Staking rewards are a byproduct of the proof-of-stake (PoS) consensus algorithm.

Launching the staking feature will purportedly let Trust Wallet support proof-of-stake cryptocurrencies. Additionally, Trust wallet added support for Tezos (XTZ), and is planning to include support for staking in the Tezos on-chain governance mechanism.

In late March, Coinbase Custody, which provides storage facilities for institutional investors, revealed that it is seeking to expand its suite of services to include staking of Tezos. Through its offline storage service, investors will be able to participate in networks such as Tezos using Coinbase as a regulated intermediary.

As Cointelegraph recently reported, XTZ had been one of the strongest altcoins in the few days prior to March 30, as its price had been buoyed by some fundamental events. The community held voting on the protocol proposal that will decide the upgrade of Tezos, and the proposal is now entering an Exploration Vote Period.

Russian social media giant Vkontakte (VK) has launched an internal currency, VK Coin, that can be “mined,” local state-owned media outlet Tass reported on April 1.

The move follows recent reports this week that VK was launching a bespoke cryptocurrency. The official information provided on VK Coin, however, does not indicate that the coin is based on blockchain technology. It does, however, encourage users to “mine” the coin via VK’s services.

The service works via a mobile app clicker game that lets users earn the internal currency, send it to other users and compete for a top winners list, based on VK Coin holdings. The service is available for iOS and Android, according to Tass.

Generating 0.001 VK Coins on a default, the game lets users spend the coins to buy boosts that enable faster mining.

According to a post from VK’s internal payment service, VK Pay, VK Coin users will soon be able to exchange their coins for various services and discounts with external partners.

By April 5, VK Coin mining has been used by more than 4 millions users, while the richest user has mined over 890 million coins, VK Pay noted.

According to local media outlet TJ, VK Coin users have started exchanging their coins for fiat money or services, such as posting ads.

VK declined to comment on whether the new coin relates to or is planned to relate to cryptocurrency or blockchain, telling Cointelegraph that the firm does not “comment on rumours.”

On March 31, Cointelegraph reported that VK was considering developing its own cryptocurrency with features much like those of VK Coin.

Meanwhile, rumors that fellow social media giant Facebook is also considering launching its own crypto have been developing since December 2018. In late February, The New York Times reported that Facebook is working on a highly secretive crypto project, planning to develop a stablecoin that would incorporate Facebook’s three fully-owned apps — WhatsApp, Facebook Messenger and Instagram.
