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 because 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.
I thought it was something that became a bad thing for the users of the bitcoin, if they don't contribute in the growth of the bitcoin. For if it does happen then I'm sure the price will come down increasingly bitcoin due to shortage of bitcoin because most people prefer to keep price stability than holding bitcoin so as not to decline
