People says 1 BTC will be cost 1 Million do you believe in that?
It is possible but it would take many years for it to become a reality. 1 million dollar for a Bitcoin is a very high value so there will be a great resistance to it and would take a very long time to be reached. A very high number of demand is also needed in order to attain that price so Bitcoin must be known by many people. And these people should be holding some Bitcoins. If these are met, we might see Bitcoin within that range.
Besides how many people rare going to resist the temptation to sell way before that, it is impossible but if bitcoin reached those prices I know that I will probably sell when bitcoin hits 100k, I do no have a lot of bitcoin but I know that if bitcoin reached that price my life will change immediately and since that is exactly what I want of bitcoin then I know that I will sell at that point.
