Yes, it seems that Bitcoin transactions are done very quickly and accurately. However, it is not really popular, so it is difficult to pay with Bitcoin for your services daily. I think the bank's transactions are fast and convenient for you. But maybe the services you need are not fast enough to update
We can't really compare bitcoin to banks because bitcoin is automatic while bank has a 3rd party to verify transaction.
In general, bitcoin is not widely acceptable yet, so whether we like it or not, bank is still very useful compared to bitcoin if use as a payment system.
We have our individual interest in life, like me, I like to gamble and when it has to pass through my bank account, it's not fast as I will just send from my bitcoin wallet, I'm just lucky that we have a lot of gambling sites there that accepts crypto already.
