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.
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.
But i guess that it's a good selling point that you will always need some kind of bank that takes a fee when you send fiat money. It's just not often that much, depending where you are sending it to and from what kind of account. And sure, sending it from your own wallet is cheaper than with banks any day.
And selling point for fiat money on the other hand is that banks have lots of more safety measures in place, than one person without any tech skills could provide for themselves.
