Bitcoin seems to be ready if one day it will be used as a world currency, the drawback until now is still the same, namely its unstable value so that there are still many people who don't believe in Bitcoin. Surely many people are afraid if BItcoin suddenly disappears just like that, especially with a fairly large value it will certainly be very detrimental to the holder. But if we look at it from the past until now Bitcoin continues to show its strength with better performance and is able to survive until now amid the many new coins that keep popping up.
