At the beginning of this year, the SEC approved the first bitcoin ETF spot, which led many to speculate that Ethereum is the next one and even some applications from Fidelity, Bitwise, and Grayscale, but what makes me doubt that this will happen soon is

• The presence of ICO, NFT, and DeFi tokens on the Ethereum blockchain, and many of these tokens have been linked to fraud.
• ETH staking, as there is an additional return from holding Ethereum.
• Securities and Exchange Commission is investigating whether Ethereum should be classified as a security

I believe that all of these reasons are enough to delay the approval of the Ethereum ETF during this year. Do you think my fears are real?

Buying LTCN means owning about 0.085 LTC per share with a NAV of approximately $9, and with the SEC announcing its lack of intention to approve new ETF products, which means it will be difficult to convert it to a converting to spot ETF during the coming period, all of these must put pressure on the price. However gains are strong, does anyone know why or am I missing something?

With the widespread spread of cryptocurrencies around us, we may find many who have invested directly or indirectly in cryptocurrencies, and some of us use our computer that contains some crypto wallets or even use it with hardware wallets, following advice such as using an open source operating system, not downloading random applications, buying Hardware wallets, using a strong password to encrypt the wallet file is necessary, but some of us are random when it comes to USB flash drives or random plug cables, where a friend asks you to charge his phone or send you pictures or movies, or even in university life by sending PDF files.

You think that as long as you do not open a USB flash drive file or run an antivirus or do not install these files, you are safe, but some of them are able to logs your keystrokes or even copy some files from your computer without your permission.

Many of these tools are not sold as hacking tools, but their design allows hackers to misuse them. Here are some tools that may do this:

1. O.MG cables



They look like normal charging cables, but they contain a small computer that can record all your keyboard clicks and can know your Wi-Fi password, or even your wallet password.

2. USBKill devices


USBKill devices are little dongles that look like USB flash drives, but instead of storing data, they send circuit-busting electrical charges into the devices they are plugged into.

3. USB Rubber Ducky

While the tool looks like a regular flash drive, the Rubber Ducky can be programmed to "type" commands into any device it's plugged into.

4. LAN Turtle


They may look like an Internet adapter, but they can collect a lot of data about you.

One of the suggestions to enhance your privacy (if you do not want to use mixers, Coinjoin Whirlpool or Jointmarket) was swapping your Bitcoin to Monero and back to bitcoin, but is your privacy definitely enhanced?

I will pose 3 main challenges:

If your Bitcoin address is blacklisted, how will BTC/XMR/BTC solve this problem, because you are simply pushing the problem to the other user.

When you exchange XMR to BTC, you may receive Bitcoin from a blacklisted address. Will you exchange it again or use a mixer?

There is a possibility that you will receive the same BTC especially in the case of P2P or if the exchange you are using to exchange XMR has a limited BTC reserve.

scammers take advantage of the laziness or ignorance of most of us in reporting phishing links, so they create armies of them and pay money for advertisements to convince you to provide them your passwords, account numbers, seeds, or private keys. Here, even 2FA will not help you, as they can create a login interface similar to the site and request a 2FA code.

If you come across any phishing link or you suspect a phishing link, do not be lazy to report it and you can do


1) Report to Google:

• Go to https://safebrowsing.google.com/safebrowsing/report_badware/?hl=en.
• Type phishing link URL.
• Complete the CAPTCHA.
• Write a reason for your report.
• Click Submit.

2) Verify the domain registration date.

• Go to https://who.is
• Type phishing link URL.
• Search for Registrar Info
• Go to Registrar name website and look for a ‘report abuse or fraud’ or use abuse@Registrar_name.com

Recently, Bitcoin fees have increased significantly, and because many beginners want to confirm their transaction and do not know how to calculate fees, so they pay more fees. In this case, a user paid 648 sat / Vbyte, and after a few minutes he discovered that the transaction had not been confirmed, so he increased it to 1116 sat, then 1,293, then increasing it to 1,585, then finally confirming it with 7,895 sat/Vbyte. Thus, instead of paying $30 to confirm the transaction, he paid $367.



So, how will we pay the ideal fees according to the situation, meaning that we do not pay a lot of fees and that they are not less than what is required, which causes a delay in confirmation?

First, we need to know the types of addresses. In Bitcoin, we have the following addresses:

• Legacy addresses: starts from 1
• Nested Segwit addresses: starts from 3 (but not all addresses that start with 3 are Segwit)
• Native Segwit addresses: starts from bc1q
• taproot addresses: starts from bc1p

Now that we know the type of addresses, we need to calculate the input and output virtual size, which we can calculate easily through https://bitcoinops.org/en/tools/calc-size/

Now suppose that I have a Segwit type transaction that contains 1 input and 2 outputs, the total size becomes: 140.5 vbytes.



After you know the size of your transaction, you need to go to https://mempool.space and choose the appropriate fees according to Low Priority Medium Priority High Priority

Suppose I want my transaction to be confirmed quickly, so I choose 42 sat/vB

total fees will be 140.5 * 42 = 0.00005901 BTC which is $2.71 If your wallet recommends higher fees to you, you will most likely pay a higher fee than what is required to be confirmed.

You can go to the two sites above and modify the transaction according to its type and the appropriate fees at that time.
