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?
I don't think bitcoin popularity will last for the long run if the price would become stable for its possible certain amount. The market will become dead and there is also a zero growth for the numbers of investors. And aside from that its popularity will not be as same as today but it will be taken by an altcoin which can have the ability to take over the rulership over cryptocurrencies.
And this will be the totally truth about the rumor against bitcoin which the term "bitcoin is dead"
Try to remember what the reason make the world be surprise by Bitcoin? Is the profit, the percent growth of Bitcoin? So, if the Bitcoin price become stable, only that time the government accepted Bitcoin is the primary currency or important asset like Gold can help Bitcoin won't be die. Other situations all make Bitcoin will be die by the community.
