Banks keep disappointing their customers all the time. In my location, banks have become the enemy of most people, the situation is so bad they will prefer personally saving their own funds using the local piggy bag.
I won't be surprised in the near future when crypto banks will replace or have the majority of users than traditional banking systems.
Actually, maybe it depends on how one looks at it, but keeping money in a local piggy bank will also eventually go back to traditional banks. or not doing something like this actually still requires a traditional bank.
The reason is quite simple, when money is kept for a long time and when there is damage and money that is no longer being produced, it will still go to the bank to exchange it, so believe it or not, doing something like this actually still needs traditional banks.
As for conditions where crypto is currently experiencing quite good developments, but in my opinion things like this still won't make any conditions change.
The conditions are quite simple because indeed seeing from whatever the intent of crypto is clearly not for that, the bank's interest may indeed decrease but when it comes to changes to be honest I doubt it.
