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?
if you look at the current state, I do not think bitcoin will be enough to meet the criteria as a digital currency.
will be the next time a bitcoin really becomes an official world currency, I think there will be a next generation of bitcoins capable of being created.
besides, many other coins also we can use like Ethereum.
