This is the most interesting event to happen in the future as I believe that bank will adapt crytocurrencies in the future to retain their profit.
As cryptocurrencies will surely rise in the future and will become a big threat to all banks and if they will not adapt to it, bank will surely loss some profit in their side. So It's better that they will unite and earn from it also.
I believe so far, we are already beginning to gradually see the coexistence already has a lot of banks are now at least trying to be a part of the growing system and then see how they can benefit from it which I am sure we will get to see more of as time goes on.
Times are changing, more developments are coming, and there is every chance this market is also going to end up being one of the top international markets in the long run, which I am sure the banks will not just want to stay on the side lines, they will also want to participate in the stream of events.
