#看懂K线 **Bitcoin (BTC)** is the world's first decentralized cryptocurrency, released by Satoshi Nakamoto in 2009. It operates on blockchain technology, generates new coins through 'mining', and facilitates transactions via a peer-to-peer network without the need for intermediaries. The total supply of Bitcoin is capped at 21 million, which gives it scarcity, often referred to as 'digital gold'. Its decentralized, tamper-proof, and transparent characteristics have garnered global attention, being used for value storage, investment hedging, and accepted by some merchants as a means of payment. Bitcoin's price is highly volatile, posing significant risks.
