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.
"once paper money will have no value" can you tell when that will be! Digital Payment is gaining popularity no doubt but it is not even close to a fraction of people using fiat till now, btc is valuable and very popular but who knows if btc will be the currency that will be chose by the majority to transact with,
Nowadays many countries are coming up with their own digital currency which means they have no intention of accepting btc as number one digital payment option.
