Digital currency is a type of digital money that uses encryption for security. Bitcoin is the most popular example. Cryptocurrencies lack a central bank control, making them free from government control.

To own crypto, a digital wallet is essential. This wallet stores your digital coins securely. You can buy crypto on exchanges like Coinbase or Binance. Keep in mind, crypto is known for high volatility, so careful consideration is advised. Understanding crypto can lead to exciting opportunities.
