It’s not that Bitcoin or any alt coin has X paper value right now, it’s nobody can get out without someone else getting stuck holding the bag. The underlying system is predatory because mining isn’t free so it’s a negative sum game where people have already cashed out.
I remember being saddened when it was less than 1/1,000th isn’t current value I realized how many suckers where lining up for the fleecing. I briefly thought the odds are very good it’s going sky high, but I didn’t want to be part of someone losing their retirement when things eventually fell apart.
