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.
