I think its true that crypto will be the future of currency. Mass adoption is coming and in fact some countries are already adopting it gradually. If you think about it, crypto is actually a good thing. If only people will be informed about its nature, how it works, its uses and advantages, there will be no need in forcing them on it, they will use it freely.
The ordinary people will never care about the future if there is no special benefit from this technological update. Only big companies will take this seriously and share their ideas with blockchain companies.
There was a time when FUDs have taken the market under control. When bitcoin and other altcoin were showing an increase in their prices, negativities took their heads up. And see it now, mostly people are happy with these coins. They are buying them and putting trust in these phenomenal coins. Hence, we are optimistic about future of crypto. The user world would be voluminous in near future.
