we don't offer financial advice, but I can provide some insights into factors to consider when choosing cryptocurrencies to buy:

You can buy cryptocurrency using a crypto exchange or through certain broker-dealers. Once you own it, you can store, manage, and even buy or sell your crypto in a wallet.

After setting up an account and transferring your crypto to the exchange, you can place a sell order, specifying the type of currency, the amount and your asking price per unit.
