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.
Wonder which wallet they are using to make these kind of blunders. I have used majority of the desktop wallets that are available in this space and you cannot make these silly mistakes using them, unless you use some mobile wallet and you are under the influence of alcohol or something similar you might make these mistakes.
