The number of bitcoin is only 21 million, is that enough for the future?
given the vision of bitcoin to become world currency?
what do you think of this?
The number of bitcoins is fixed, it has only 21 million, but only a tiny fraction of the currency is in circulation, and some of it has been lost. I think that's enough, because the unit price is so high that many people don't have enough money to buy a bitcoin.
