With blockchain data can be stored in a decentralized public book.
With cryptocurrency, we can make anonymous transactions without centralized intervention.
If you add speed and spread to the public, then the future is cryptocurrency.
How do you think?
I think I would say, the future of cryptocurrency is not fully achieved because from all the happenings (scams etc) so far shows that the cryptocurrency space needs more advancement, improvements, hardwork from the teams, and so on; in addition, of course speed and spread have a lot to do with the future of the cryptocurrency space. The process of performing a transaction and waiting for a long time for it to be confirmed is a discouraging factor thus once taken care of, we can to a very great extent agree or say cryptocurrencies has a good and confirmed future.
