How to buy/sell bitcoin?

You can buy or sell bitcoin via an exchange. I use CoinBase but there are many others.

CoinBase

Gemini

FTX

Binance - Not available in NY state and I don't trust them because they took my social security number even though I couldn't sign up.

Most of these will require you to provide this type of information and maybe even a drivers license.

You can also buy Bitcoin or Ethereum via an ETF (Exchange Traded Funds) via a broker like Fidelity.com.

GBTC - Greyscale Bitcoin Trust

ETHE - Greyscale Ethereum Trust

GLDC

BITO

BTF

If you buy via a broker/ETF you won't hold the coins, and in some cases, the coins are backed by future contracts.

You can also buy Bitcoin or other cryptocurrencies via a DEX (Decentralized Exchange)

Uniswap
