If you are that interested, I would spend just a little bit on them just to mess around, but keep in mind that you could lose it at any point. (EDIT: Their minimum package is 100 euros! Maybe don't do that :) )This Wikipedia article has enough info on Onecoin for anyone to see that at least a little shady business is going on. Most of their "educational material" is plagiarized, and all of those associated in its operation have been involved in suspicious ponzis in the past. I would just stay away from it. It only survives on the uninformed and desperate.
