Bitcoin payments are irrevocable, which means that once you’ve paid, you can never get them back. If you have been cheated in connection with a payment you made, there is no authority or body that can help you get your bitcoins back. Your bitcoin is stored in a code-protected e-wallet. If someone stumbles upon your code or can hack your wallet, your bitcoin will disappear. It can be compared to the loss of a wallet full of cash.
