When people talk about the benefits of bitcoin over Fiat money, one of the biggest advantages is that bitcoin is more secure and the bank has not control over your money. Generally, people talk about the lack of 3rd party.
Give some examples of the problems with banks you have faced that there wouldn't be if cryptocurrencies existed that time.
The biggest problems that I have faced with banks is how slow they can be especially on the weekends, bitcoin in the other hand is way faster than that because you can decide how fast you want your transaction to be confirmed thanks to the fee that you are paying to the miners.
