...not a guaranteed value of the Bitcoin makes the price move is not fair.
Life is not fair. The fact that bitcoin is not guaranteed by state violence is the very reason it will succeed, the very thing that makes it unique from all violence-backed state promissory scrip.
No, bitcoin will not last forever. But it will almost certainly get us through the end of capitalism.
It is difficult to know the future of Bitcoin, as it has nowhere to go in the future, now many people have withdrawn from Bitcoin because of the risk that too much, what they want from Bitcoin is a quick profit and that is not a Bitcoin fan, I will continue to invest and buy Bitcoin until it or I will not exist
