Bitfinex just spent $23.7M in fees to make a single Ethereum transaction
So, how do you cancel a transaction with such an obvious mistake when it is recorded on a blockchain?<p>(This is a rhetorical question.)<p>EDIT: Why the downvotes? It's not okay to discuss the fact that in the possibility of human error (assuming this is one, and not a very wild —yet successful— bet on a laundering attempt), the incapacity to cancel transaction may be a problem?
