calling bitcoin a ponzi scheme
but I still call it a huge bubble
If you couldn't figure out something as simple as why a Ponzi scheme is how do you expect to figure out what a bubble is. The concept of a bubble is much simple than the concept of a Ponzi scheme!
We can't expect the idiot to understand simple financial and economic terminology if he can't even figure out how to use the forum. He can't even reply to his own thread, so he starts a new one. Pathetic...
