First i must say some people are very stupid indeed. People talk now because When Bitcoin came out way back 2008 people said that it was ponzi nobody gave a hoot then. When i was reading all the comments here. I am really shocked to see people saying this is ponzi. It is obvious people never learn from mistakes.
Plus it is 2017 and the coin keeps increasing. I wonder who's now the idiot. Please don't buy sef. Right now i can exchange 1tbc for 4.9 BTC. Mehn i don't care am not SELLING to anybody.
