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.
It's a gem and gold for everyone. But if you think that the government isn't doing steps to deal with bitcoin, they're already on the move. At least for some countries and others might have been already doing something that we don't know.
The step of the countries that are also stepping into cryptocurrencies, they're not going to use bitcoin but their very own made crypto which is called CBDCs. Bitcoin was the inspiration of that development, you can search the meaning of it on wikipedia.
