Re: Bitcoin would have averted this painful loss, shame on fiat
Bitcoin is boss, not by mouth only, you see what fiat cost that innocent guy trying to do a legitimate trading business. His money was useless for him by fiat bank arrangement, no one knows where the actual fault came from due to too many parties involvement and the banks will do it authoritatively, they set the price and charges as they like on your own money. This can't happen with Bitcoin, all transactions are transparent, you can easily know where the fault comes from and less than $0.3 will complete the transaction in minutes.
Is it really true that something like this can't happen with bitcoin? 
I paid as a fee over 0,7 btc. I can see the wallet address it was sent to. But i do not know how to find out who confirmed this transaction and who got this fee. Is there any way I can try to return it and how?
The bank transfer must have delayed his transaction for at least two days only to realize that almost €100 was charged for transferring €1,000 to the beneficiary account. Fiat is just silly, banks are crook and feeding fat on people's money.
The traditional banking system is not perfect (note, before the advent of bitcoin you all silently used this system) and the world has not abandoned this system yet. But bitcoin too has its shortcomings. You somehow quickly forgot about last year (or so) of BTC-mempool load and the resulting transaction delays and high fees. You should not overestimate bitcoin, as well as underestimate fiat, but rather take a realistic look at existing financial instruments and use the advantages of this (having leveled out the disadvantages by using alternative solutions).
