is it a ponzi or is it a buuble?
Make up your mind. For example bubble was the marihuana stocks. Ponzi is when there is no inherit value or utilty in the asset and it keeps growinf till it goes to zero when everyone founds out.
BTC could be in a bubble, but it is not a ponzi.
that not all bubbles are ponzi and not all ponzi are bubbles. Bitcoin holders are never harmed by a drop in price if they keep it for a long time. Meanwhile, what is called a ponzi is a fraud under the guise of an investment business that seems profitable.
