I mean its only 21million btcand there are 6billion people in the world , how can it be enough
Ofcourse this amount of bitcoin will be enough for the bitcoiners of the whole world and also for the newbies who will enter on the bitcoin job .
Here the amount of bitcoin is not a big matter because if the numbers of the bitcoin per user became down then surely the price of the bitcoin will increase , that will be solution for the limited supply of bitcoin .
So here all over it is not a big matter whether the 21 million bitcoin is limited supply in the bitcoin market .
