I wonder this: if the usual banking system will disappear as such, then she will leave and credit system, leasing and installment payment, debt, etc. As there is no centralized authority that can issue and track correctness of performance. To some extent, this is certainly good, but in fact people who can not immediately earn a large amount of money and will remain in the lower levels of life, which gives the modern banking system (though not ideal). What do you think about this? How to Take a loan in cryptocurrency?
Bank will never dissapear, country need bank to gather fund from the citizens, that fund will be used by industries to produce more product then improve country economy. But the there will be a big changes in term of bank profit, more people will use cryptocurrency and make it's price rise because of the demand that they made and bank profit will be decrease because credit card will not be used anymore.
