There are two you possibilities available in this situation Oneness banks will accept the Bitcoin and make it as transaction and payment and the other way is they don't want to take it as a legal payment method definitely one thing will happen in the future.
They will definitely adopt it, there is no other choice for them. ignore bitcoin will make them run on the spot, because innovation must
continue and it can be done by adopting bitcoin, they will definitely do that..
I am glad cryptocurrency runs on a decentralized system that makes it impossible for them to be able to control, as time goes on, what will prompt them into adopting crypto is when they see a massive adoption of crypto beyond control and large decrease in the number of people that uses their traditional system.
I really don’t know why banks are having issue with a system that would even benefit them and make their already existing system a better one, if they can incorporate this system into theirs too, it will make them have more users and there will also be more funds for them, I am sure they have no problem with crypto, they are just being careful since they operate under government, because if they had problem with crypto, how come most of the banks recognizes XRP.
