The bitcoin fees market is getting out of control. Someone must've been really in a hurry as they paid BTC19.82 (~$511,000) fee just to send $2k worth. Jokes aside, probably a very painful mistake. I wonder how's it going to unfold and whether the miner will return it to the unlucky sender.
I doubt it's an act of carelessness, anyone with kind of a balance would at least know how and where to input the appropriate fees. It could be a way to donate a large sum to the bitcoin miners.
