That's the advantage of Bitcoin, you have to admit it, Bitcoin is not only used for investment, trading and so on, Bitcoin is a digital currency that is currently being used and sought after by the world community, be it transactions with real goods such as in malls, restaurants, etc.

Bitcoin is an asset that can be traded in two markets "crypto market and exchange in real market" as I said above.
The bottom line: you have to admit that for now Bitcoin is one of the most popular digital currencies in the world, its prowess exceeds the currency of every country.

You have ever come across currencies of other countries that cannot be used in certain countries, however, not with Bitcoin all countries accept it, are you sure about that.
