bitcoin could be the world's currency, but maybe not.
In my opinion, Bitcoin has great potential to become a world currency, but it's just that many countries still don't legalize Bitcoin and other cryptocurrencies, from this reason it becomes a bit of a serious problem in adjusting Bitcoin to become a world currency, but I see that many countries have accepted Bitcoin, there are also countries that must first exchange it for local money and there are also several countries that do not need to exchange it for local money.
bitcoin is now increasingly popular and some have adopted it as in the country of el Salvador, it is possible that other countries will also be interested and adopt bitcoin together and eventually become a world currency.
You are right, Recently many countries have adopted Bitcoin, the level of popularity of Bitcoin is increasing day by day which of course will have great potential for several other countries that have not yet adopted Bitcoin, maybe they will do it, maybe even in the future. later many countries will legalize Bitcoin, and this is also our hope.
Basically Bitcoin is the world's first considered digital currency.
but, in my opinion, both are equally important. For example, as a store of value, a medium of exchange, and a unit of account.
Yes of course, and one of the most Valuable Storage Assets is Bitcoin, I think this can't be doubted anymore.
