Bitcoin is a decentralized digital currency created to enable transfers of value over the internet without relying directly on banks or other intermediaries. It runs on a blockchain, a public ledger that records and validates transactions through a global network of computers.

Its supply is limited to 21 million units, which sets it apart from traditional currencies whose issuance can be changed by monetary authorities. The network’s security is supported by cryptography and mining, a process in which participants validate blocks of transactions.

BTC can be used as a means of transferring value and is followed by investors around the world. However, its price can fluctuate considerably over short periods, influenced by supply and demand, economic conditions, regulation, and market sentiment.

Before trading Bitcoin, it’s important to understand the risks, protect your account with two-factor authentication, and never share passwords, codes, or recovery phrases.
