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.
you've probably not considered a scenario where you mistakenly sent Bitcoin to a wrong address and can't lay a complain to anyone because the system is void of such provision. System errors are part of what you expect to see in both centralized and decentralized financial system. The manner at which they happen might not be the same but the reality is that things do go wrong and sometimes it's not always because fiat has a very bad nature that causes it. Sometimes, while trying to paint Bitcoin as a good asset, we can always do so without speaking down on the fiat or trying to point out the errors that's associated with the fiat as it Bitcoin is 100% perfect.
If we begin to make a comparison of minor limitations like this from people's experiences while using either fiat or Bitcoin, we will certainly have a lot of stories to share from both sides of the coin. Either you're using fiat or Bitcoin, you just have to ensure that you're careful enough not to get into a situation that causes you to experience any form of loss.
