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?
No, it wouldn't. Current popularity is, first of all, because of extra growth which I cant compare with any other kind of asset. All that tittles in mass media "bitcoin broke 5k", "bitcoin broke 7k" and so on are the reason of bitcoin popylarity.
