Do you think if BTC had a stable price which could only be altered by $0.01-0.10 it would still be as popular and as used?
Of course bitcoin will remain popular. because it is a digital currency, different from fiat currency.
No there will not be any popularity for bitcoin. Being digital dont make bitcoin famous, it is the high profit percentages that it gives to its users and this is the only one reason for which bitcoin is being praised by everyone here. And when you talk about being stable or not, believe me the instability is the only one key for bitcoin for this much fame else it will be like any other fiat currency.
Bitcoin is the future of the world economy as well. Bitcoin is not going to decrease in popularity in any way if it became stable because it has still price more than that of gold and diamond. Bitcoin is the one which is soon going to be made legal throughout the world just because of the amazing profits it is providing to the bitcoin community and many countries have already made bitcoin legal.
