Cash and crypto have similarities. Crypto isn’t controlled by an individual, institution, or any other authority. Cash is issued by a government. Crypto is not. They both have a market value and some cryptocurrencies, like bitcoin and ethereum, can act as a medium of exchange—but beyond that, they’re quite different. Cash is issued by a government. Crypto is not. Instead, it’s managed by blockchain technology and verified by all its users on the network.
Digital cash transactions (like paying for something or sending money to a friend) are made through a third party (like a bank or financial institution).
You can withdraw cash. Crypto only exists digitally and can’t be physically withdrawn. So, you’ll never actually hold a bitcoin in your hand like you would a $20 bill.
