and the fact that there are some places where they will not accept fiat makes it easy for bitcoin to make it up to this market cap. The fact that I know bitcoin is digital also makes it obvious that bitcoin can definitely reach here.
Do you mean that there are places where they only accept a specific fiat currency hence why bitcoin's popularity is increased because it can be used as is by anyone in the world?
because if so then yes I agree with your statement. Now just imagine if more countries weren't hostile with bitcoin and accepted it as a legal tender. More people across the globe will definitely use it.
