I am reading this article by MEW and they mention that in period of BAT token sale someone paid $6k for transaction fee: https://kb.myetherwallet.com/gas/what-is-gas-ethereum.html, and they quote how transaction that costed $6k failed:
That's right. Someone paid $6000+ to send a failed transaction. Ouch, indeed.
What was the reason he failed? did he supply too small gas price with infinite gas limit or too small gas limit with enourmous gas price?
