75.9% ( 15,947,975 bitcoin) of the bitcoin is already mined so to circulate bitcoin all over the world there is only few bitcoin beggar many bitcoin user are holding bitcoin and waiting for price hike. So what would happen if the continue holding and we are left with only few bitcoin to circulate. So can it act as global currency or we need some modification.
* this is a duplicate topic.
and you have no sense of what you are talking about. 16 million bitcoin is 10.4 billion dollar and there is still 5 million more bitcoin left to mine. and as long as there is a circulation there will always be someone who is selling and someone who is buying.
