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.
Honestly there might just have been a mistake from either the sender making a mistake of adding an additional figure when he intends to press just only one or maybe the mining pool used broadcasred his transaction across other addresss who's transaction fees are higher making it appears that way, but since it's an open transaction we don't know which miner will claim this to add as their block reward, the error that happened could be traced down to the sender and not the network.
