將 Bitcoin (BTC) 兌換為 US Dollar (USD)

Bitcoin is a decentralised cryptocurrency that lets people send and receive digital assets without banks. It runs on a public blockchain, where a distributed network records and verifies every transaction. The network uses proof of work to secure transactions and issue new coins. New Bitcoin is created through block rewards, which halve roughly every four years, slowing supply growth. The total supply is capped at 21 million coins, which is why Bitcoin is often used as the benchmark asset in the crypto market.

The BitMEX BTC to USD converter shows you the current Bitcoin price in US dollars using live market data. Just enter any amount of BTC, and you’ll instantly see what it’s worth in USD. The converter pulls prices from active trading markets, so what you see reflects real-time conditions. You don’t need to create an account to use it.

Federal Reserve policy affects Bitcoin’s price through interest rates and liquidity. When the Fed cuts rates or adds liquidity, more capital tends to move into assets like Bitcoin. When the Fed raises rates or tightens liquidity, the US dollar often strengthens. This shows up in the US Dollar Index (DXY), and a stronger dollar usually puts pressure on Bitcoin’s price. Bitcoin’s supply is fixed and doesn’t change with Federal Reserve policy. New Bitcoin enters circulation at a fixed rate, and halvings reduce that supply growth over time. Strong rallies often happen when liquidity increases while supply growth tightens.

Spot Bitcoin ETFs affect Bitcoin’s price by directing large amounts of capital into the spot market. Since their approval in the US in January 2024, they have made it easier for institutions and retail investors to gain exposure without holding Bitcoin directly. ETF inflows and outflows now act as a key price signal. When ETFs see strong inflows, the issuer buys Bitcoin in the spot market to back those shares. This creates sustained buying pressure and reduces available supply on exchanges. When flows reverse, that demand weakens. Large funds increase this effect. Products like BlackRock’s iShares Bitcoin Trust (IBIT) have attracted billions in assets, making ETF activity a direct driver of Bitcoin’s price.
