Why not? We can see rapid use of bitcoin everywhere. Then if it used largely it will be an international currency
But, i think it's verry impossible, couse bitcoin have many weakness like anyone can get it with verry easy. And if wold be, that can make bitcoin unlimited, so if all people have so many bitcoin, it will make bitcoin verry cheaper after.
Bitcoin could end up being a side nation's country money but the fact of the matter is... You cannot expect btc to rise to the challenge to be that currency because there are a limited amount of btc allowed.
If bitcoin is limited , So How much a person have a maximum limit?
well one person can have 21m bitcoins thats the total amount of bitcoin when it started but now that wont be possible
and the maximum amount of btc a person can get is the total of the remaining funds of bitcoin. we already have the
first halving and second is coming up so the remaining funds of bitcoin will right about 5.25m (bitcoin excluding the lost and mined
coins.) after the second halving.
