Those who have already figured out the issue understand that any crypto currency is not even air, it's nothing that rests solely on the faith of those who invest their own resources or funds in an almost "ideal" system of detachment.
As for me that the future of Cryptocurrency we can say Cryptocurrency and blockchain technology are here to stay. Thats the future. Instead the concern we should have is how blockchain technology might not be used well in this future because in the future many people will join with it in the future.
