The future of a product ,any technology , will depend largely on the customers and investors , if they are still trusting and patronized cryptocurrency and continue to support the technology ,it will have a good future in several years , if there is no demand in the market what will happen to the supply, so it is in hand of the users the future of cryptocurrency.
I agree.The future of bitcoin will depend more largely on the people itself,its investors and even holders.I believe that bitcoin will soon to be a global currency,making fiat currency lessen its usage.And for sure along with the growth of bitcoin,economic growth will also takes place.
