Transaction of $13 worth of ETH with a fee that is worth $200k! Damn! Thats a lot , I just dont really get what happened right there. Why would anyone do such a thing, if it was intentionally ?
Im not going to make such a mistake unless the wallet Im using doesnt show me the fees they charge for a transaction. Im always very careful when making transaction and by the way such a thing has not happened to me before, despite I have made use of several wallets. Maybe these guys chose a custom fee and they were aware of it.
It was 291 btc of fees 
Was it a mistake or they are all just doing it ? Im not going to make such a mistake unless the wallet Im using doesnt show me the fees they charge for a transaction.
