"Bitcoin made rich just a few but it ruined many"
Look, Bitcoin is zero-sum. For every win, there must be a lose. Somebody has to put in cash and not get it back. Bitcoin needs a lot of
suckers losers to keep it going.
They're called HODLrs.
This is not necessarily true. Some people have legitimate needs for money when they sell their bitcoin so even though they lose out on further price appreciation they get something they were in need of.
This is a difficult concept for some folks. You see it predates the 1980's, the time when credit card offers filled mailboxes from sea to shining see. It was before home equity lines of credit and sub prime lending. There was a dark age in history when people would actually save money.
