This topic was started November 17 last year. I wonder if the thread-starter still thinks that bitcoin is still a Ponzi Scheme. I wouldnt be surprised if this person is into cryptocurrency now.

In fact who or what gave you the idea that bitcoin is a ponzi scheme in the first place. I see a lot of people out on the street think that and I just don't get it.
