I call Bitcoin a gem. Because once paper money will have no value. The only reason behind not having the price of paper money. People's interest is changing day by day. Now people are leaning towards digital transactions. Now no one wants to do cash transactions. That is why the importance of cryptocurrency has increased a lot.
Bitcoin is a currency. Which you can use it for any purpose at any moment in any place. Just one transaction. In my opinion, the government of every country should give legitimacy to cryptocurrency. Has already given legitimacy from many countries.
I think thread poster is talking with reference to fiat replacement yes bitcoin has this potential but personally i think at the moment it is more accepted as a store of value so it is kind of replacing gold and silver for now to be real fiat replacement it has to come up with efficient network and get rid of the scalability issues.
