Many reason why a lots of people accessed and used bitcoin, actually it is a business that has proven and tasted of being an instruments of making money. However if price of bitcoin become stable, the answer is only a form of speculations, because no one can prove that bitcoin price in the future become stable. If we based for the past years of bitcoin operations, not even once that bitcoin price become stable.
Its true that past performance of bitcoin matter but I think bitcoin is almost new in market and still there is a lot of journey to do by bitcoin and there is no chance that bitcoin price will be stable because they bitcoin is going to achieve its goals so it seems like that bitcoin price will go more high and I, m sure that bitcoin will be the last currency in market and there will be no other crypto in market.
