Can you cancel or reverse a bitcoin transaction?
Let’s say you’ve made a mistake and sent your BTC to the wrong address. After googling for a solution and reading FAQ sections on Coinbase and blockchain, you will most likely decide that your transaction is lost forever. But, in truth, you still have a time to reverse it: recently Blenderwallet.io (wallet from the creators of the largest bitcoin mixer) added a new feature – “Transaction discarding” based on RBF(Replace By Fee) protocol.
