1. Last week, @robbietilton sold this art piece for about 17305$ on @withFND.
I saw a lot of people asking questions on CryptoArt and NFTs (Non-fungible token) to understand how it works. I'll try to explain the basic concepts on this thread ↓

Some thoughts on this super inaccurate piece.

tl;dr: this is not a defence of Tether/ iFinex, who I would like nothing more than to see disappear into irrelevance. However, most of the conclusions here show zero understanding of crypto market

1. First up: it’s completely inexcusable that Tether refuse to have a 3rd party audit. I can’t find a single good faith reason for this.

Bitfinex GC recently did a superb job of sidestepping that question on WBD:

2. For better or worse, USDT (tether) started as a way for people to move fiat between exchanges (a major problem) in the absence of the ability to onboard banking partners, none of whom wanted to touch crypto. USDT is now the dominant stablecoin by mkt cap & liquidity.

3. As a result of the difficulty of having a fiat on/off rail, many exchanges, like Binance, chose to be ‘crypto only’, using stablecoins in lieu of fiat. This is why the majority of inflows into BTC (article says 70%) is via USDT

4. Unbanked exchanges are in aggregate larger than banked ones. This is true, but it’s not because of a giant conspiracy to steal your BTC. Being unbanked = real regulatory arbitrages (lower cost + ability to innovate fast), and lower barriers to entry means there’s more of them.

NFT Crypto Guide 101 📚

🔹What are Non-Fungible-Tokens?
🔹What are NFTs used for?
🔹What do I expect for the NFT space in 2021?
🔹What NFTs do i hold?
🔹Where do I buy NFTs?

I will go through all of these questions.

🔹What are Non-Fungible-Tokens (NFTs)?

NFTs are crypto tokens that represent something unique. They are not mutually interchangeable.

This means that one NFT is not the same as the other.

Unlike for example Bitcoin, where each satoshi is exactly the same as the other.

These NFTs exist on the Ethereum Blockchain. Instead of ERC-20 tokens, we call these NFTs: ERC-721 or ERC-1155 tokens.

Each of these NFTs have an unique ID that seperates them.

For example, The Hashmask with ID #6718 is completely different than the Hashmask with ID #9939.

Different visually as well as the ID on the blockchain.

🔹What are NFTs used for?

NFTs are used to create verifiable digital scarcity and digital ownership.

The main applications we see today are:

🔹Digital Art
🔹Collectibles
🔹Games

1/20 Bitcoin is too slow and expensive for payments. We all know this. To solve this problem, the Lightning network is being built on top of Bitcoin's blockchain. Will it be the end of XRP?

A thread. 👇

2/20 On a normal day outside a bull run, Bitcoin takes ~10 mins to transfer, at a cost of about $0.50. Any time network activity ramps up, those times and fees multiply. Bitcoin's Proof of Work system is painfully slow and can only handle 7 transactions per second.

3/20 To attempt to solve this problem, the Lightning Network is being developed. It's a 2nd layer network that sits on top of Bitcoin's blockchain. It's been in the works since 2015. Yes, 6 years. Do you know anybody who uses it? Me, either, but I'll get to that.

4/20 Lightning works by opening "channels" between parties. Those parties can perform as many Bitcoin transactions as needed and then close the channel. Because the transactions aren't written to the Bitcoin blockchain until the channel is closed, it's much faster.

5/20 Individual payment channels between various parties combine to form a network of lightning nodes that can route transactions among themselves. The resulting interconnections between various payment channels is the Lightning Network.
