I have made bad investment decisions before, lost a lot, but will own up to it.
The guys in here calling Bitcoin/crypto a ponzi, scam, or other bs have obviously been hurt, I see this a lot. Usually it is people who bought into the hype, probably at the top or near top, having no idea what crypto is, does, used for, nor did they care. And the bubble burst and crashed down, they panic sold, thinking they're damage controlling and salvage whatever they can, sell, at loss, upset and angry, and will take weak stabs (as one loser in this thread has done already)
Then again, calling a ponzi without knowing what a ponzi is, just because "someone else called it a ponzi" also shows his character and credibility a million times through lol
