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.
Well, not necessarily more secure, with hacks, etc. And can't forget about the volatility factor. However, after moving overseas, and losing access to my online banking, I found (for my particular bank) a very difficult time trying to get into my account other than by phone (which also had its own difficulties, and I never did attempt it). Reliable cryptocurrencies, and a wallet with p2p features for trading and transferring may have made life easier. But I personally wouldn't be putting all my money in it.
Have a great day,
