## virtual current

### BTC

Its market value ranks first, and people call it "the king of 10,000 coins" and "digital gold". Its current market value is 780 billion yuan, accounting for 52% of the total global virtual currency market value, ranking first in the virtual currency market value. Its total amount is permanently limited to 21 million pieces. It is extremely scarce, and it has established a broad consensus around the world. It is a legal asset in dozens of countries around the world. Although the currency value of Bitcoin has fluctuated violently in recent years, its development momentum is still strong compared with other virtual currencies.

### Ethereum

People call ETH blockchain 2.0. Compared with Bitcoin, the main feature of ETH is the introduction of smart contracts. Now ETH is mainly used for ICO. At present, the total market value of ETH tokens is RMB 199.1 billion, accounting for 13% of the total global market value.

### Tether

Tether (often referred to by its currency codes, USD₮ and USDT, among others) is an asset-backed cryptocurrency stablecoin. It was launched by the company Tether Limited Inc. in 2014. Tether Limited is owned by the Hong Kong-based company iFinex Inc., which also owns the Bitfinex cryptocurrency exchange. Tether is described as a stablecoin because it was originally designed to be valued at USD $1.00. Tether Limited has stated that it maintains USD $1 of asset reserves for each USD₮ 1 issued, but regulators have fined it for failing to do this and has failed to present audits showing sufficient asset reserves.

## NFT

Another derivative of Web 3.0 is NFT.

The full name of NFT is Non-Fungible Token."Non-homogeneity" means that items cannot be directly exchanged for each other. It is easy to imagine that works of art are non-homogeneous. Basically, you will never see someone exchange a song for another person's painting in life. Or you can't set an exchange relationship for them.

The simplest explanation for "non-homogeneous tokens": NFT is a unique digital certificate that cannot be copied. Every NFT is different from NFT to NFT.

For example, suppose A draws a picture, and then A takes a picture of it and sends it to class B as an NFT. Then, student B right-clicked and copied a copy, and sent it to student C. At this time, classmate C said it was wrong, yours is not the original version. You are a copy. What I want is the photo that A sent you.

### CryptoPunks

CryptoPunks has generated 10,000 24\*24 pixel art image NFTs through algorithms, and each punk pixel avatar NFT has its own information, including its attribute characteristics, ownership, and circulation information. The developer has reserved the first 1000; the remaining 9000 are free for all punk pixel avatar lovers.

### Bored Ape Yacht Club

Bored Ape Yacht Club, BAYC for short, is an NFT of 10,000 ape pictures launched by Bored Ape Kennel on April 23, 2021. These monkeys are randomly composed of 10,000 monkeys through programming. The clothing, accessories, background, and facial expressions of each monkey are unique. The Boring Monkey Yacht Club is laid out on the Ethereum blockchain.

### Azuki

Azuki is a series of NFT pictures with the theme of Japanese anime style. Each NFT has differences in hairstyle, eyes, mouth, neck, clothing accessories, background type and other dimensions.
