Base on the speculation of other members here in the forum that in the near future banks all over the world will adapt the system of cryptocurrency and it will eventually centralized all banking transaction in one with the cryptocurrency or the digital currency.
You are right although I think they will not try to use cryptocurrency directly, the power of blockchain will only be harnessed to aid their system. For now it seems impossible but soon there will be institutions using blockchain without cryptocurrency in it.
Its price will be stabilized and it could be use all over the world where comfort of traveling just to use the digital currency as a form of payment.
Cryptocurrency will never be stable so long as it is traded on the free market, but it will become more stable enough to use for payment in the future.
However, it is the news nowadays has the opposite of their speculation since there are countries banning already the use of cryptocurrency. In your point of view, Will it happen to centralized money all over the world through the use of cryptocurrency? Or it will just pass and nothing will ever change in our system of banking. Or do you have any speculation with cryptocurrency? I need to justify the speculation's probability.
I think it will just come to pass(as it won't happen to centralized cash all over the world) but there will be changes in the way banks operate. At that point, I speculate cryptocurrency as something people use as an alternative, like how we use credit card sometimes.
