Everyone on the forum knows what Bitcoin is. We already know that many countries have removed this currency from the ban. I mean, will all the nations of the world use Bitcoin as a currency?
The popularity of Bitcoin is far from enough, and there is still a long way to go before it becomes a world currency.
Most countries in the world are cautious about Bitcoin, and there are still many countries that oppose the use of Bitcoin. Bitcoin still has a very high threshold, and the government cannot track transactions that manipulate Bitcoin.
And the price of Bitcoin is very prone to large fluctuations, which are very rare in legal tenders, so Bitcoin is not suitable for becoming a world currency.
