I think the bitcoin price will go up a lot in the next 50 years. There are many very good community support for it.
Half a century! that must be the longest projection I've heard so far.
and even that is not certain to bitcoin will remain viable for the next 50 years.
likely there will be a better competitor technologies. but if bitcoin can last up to 50 years ahead, it will be outstanding, and perhaps the entire world many are using bitcoin. so also bitcoin is already widely used as payment transactions worldwide.
