I think the bitcoin price will go up a lot in the next 50 years. There are many very good community support for it.
of course price is going to be pumped up really fast in the near future thus allowing us all to make some decent profit in the future, i hope i will be rich because of bitcoins
50 years is a lot of time. I doubt if we will have bitcoins by then. That time something new will be there.
Till time we will see many more pumps, of this I am certain.
