How does one buy, sell, or store cryptocurrencies?

To buy, sell, or store cryptocurrencies, you will need to first set up a cryptocurrency wallet. This is a digital wallet that can be used to store, send, and receive crypto currencies. Once you have a wallet, you can purchase crypto currencies from an online exchange such as Coinbase, Gemini, or Kraken. These exchanges allow you to connect your bank account or credit card to purchase cryptocurrencies. For added security, you can also purchase a hardware wallet, such as a Ledger or Trezor. These are physical devices that store your crypto currencies offline, providing enhanced security for your funds.
