To own crypto, a digital wallet is essential. It holds your assets and allows for secure transactions. You can buy crypto on exchanges like Coinbase or Binance. Remember, cryptocurrency is volatile, so be cautious with your investment. Learning about cryptocurrency can open up new investment opportunities.
