Cryptocurrencies are not backed by any government or central authority, making them decentralized and free from government control.
The supply of most cryptocurrencies is limited, with a predetermined maximum number of coins that can be mined or created, such as Bitcoin's maximum supply of 21 million coins.
Bitcoin transactions are irreversible, meaning that once a transaction is confirmed, it cannot be reversed or cancelled.
Many well-known companies, including Microsoft, Overstock.com, and AT&T, accept Bitcoin as a form of payment.
Cryptocurrency exchanges, where cryptocurrencies can be bought and sold, are largely unregulated, making them vulnerable to hacks and scams.
