To begin purchasing cryptocurrency, you must first locate a crypto exchange site that allows you to convert your fiat currency (cash) into coins. Because some exchanges only allow crypto-to-crypto trades, you must purchase your crypto at an exchange that accepts debit/credit cards or bank transfers.

Coinbase is the most popular exchange in the United States for purchasing cryptocurrency with cash. Binance is the most popular cryptocurrency exchange elsewhere. Both exchanges are simple to use and provide a wide range of altcoins, which are digital coins other than Bitcoin.

When paying with cash, you'll almost certainly have to choose one of the major cryptocurrencies for your first transaction: Bitcoin, Ethereum, or Tether. Then you'll have access to a plethora of additional trading pairs to get to the coin you want.
