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?
I think for now 21 million bitcoin are enough to fulfill the needs around the world, but comparing with the far future when more people will get to know it, and more people will invest in it and hold their bitcoins, the circulation will get slow between users so the limited supply will be a problem with a high demand, this will be solved unless the value increase and reach a high price though.
