What Bitcoin is and how it works
Bitcoin, launched in 2009 by the pseudonymous Satoshi Nakamoto, is the first decentralized digital currency, designed for peer-to-peer payments without an intermediary such as a bank.
The network uses proof of work: miners compete with computing power to add blocks roughly every 10 minutes, and transactions become very hard to reverse after several confirmations.
BTC supply and token economics
Supply is capped at 21 million BTC. The block reward halves every 210,000 blocks (about four years); the latest halving, in April 2024, cut it to 3.125 BTC per block.
What usually moves the price
Commonly discussed drivers include global liquidity and interest rates, flows into US spot Bitcoin ETFs (trading since January 2024), post-halving supply changes, long-term holder behavior and regulatory news.
These are commonly discussed factors, not a forecast; no single factor guarantees direction.
Where to buy BTC
BTC spot pairs are usually listed on large exchanges such as Binance, OKX, Bybit, Bitget and Gate, but pairs and availability depend on your region and account—check the official listing. Compare fees at the same volume, then check spread and slippage.
Key BTC risks
Price swings are large, with several historical drawdowns above 70%. Lost self-custody keys cannot be recovered, and exchange custody carries platform risk.
Only use money you can afford to lose entirely, and size positions and liquidation prices before using leverage.
How to read the indicators on this page
RSI14 above 70 is often read as overbought and below 30 as oversold; price above MA20 and MA50 is a bullish alignment; MACD shows momentum direction. All are probabilistic readings on 90 days of daily closes and can stay extreme during trends.
