The total amount of Bitcoin is 21 million, which is an unchangeable rule determined by algorithm design. 1. Through the proof of work mechanism and the issuance rule of half of every 210,000 blocks, the issuance of new coins decreased exponentially, and the additional issuance was finally stopped around 2140. 2. The total amount of 21 million is derived from summing the equal-scale sequence. The initial reward is 50 bitcoins. After each halving, the sum of the sum converges to 21 million.

In web development, the choice of CSS units depends on design requirements and responsive performance. 1. Pixels (px) are used to fix sizes such as borders and icons, but are not conducive to responsive design; 2.

Viewport units (vw/vh/vmin/vmax) are adjusted according to the screen size, suitable for full-screen elements and dynamic UI; 5. Auto, inherit, initial and other values are used to automatically calculate, inherit or reset styles, which helps to flexibly layout and style management.

Stable coins are cryptocurrencies whose value is linked to stable assets such as the US dollar. They aim to solve the problem of large price fluctuations such as Bitcoin. There are three main types: 1. Fiat currency collateralized stablecoins, such as USDT and USDC, are supported by the issuer's reserves of equivalent fiat currencies; 2. Money collateralized stablecoins, such as DAI, are generated by over-collateralized crypto assets; 3. Algorithmic stablecoins, relying on smart contracts to adjust supply and demand to maintain price stability. The reason why stablecoins can change the future is: 1. It is a bridge connecting the traditional finance and the crypto world, reducing the threshold for user entry; 2. Achieve efficient and low-cost global payments and settlements, greatly improving the efficiency of cross-border capital flow; 3. It forms the cornerstone of decentralized finance (DeFi), for lending, transactions, etc.
