It is funny how people assume it is a scam or ponzi!, just because someone they do not know posted scam on their youtube and website, and most people seem to believe that. But why don't you believe an actual member of Coinspace?
You should know by now that People put scam on their site on purpose, so they get more clicks and move quicker up the google ladder! Or they post scam because they want you to buy their product! People see 10 negatives on the net and assume it is not real, what about the 500.000 positives? Really take the time to do your research properly. It is sad actually because you believe a guy that you do not know who posts scam, you might miss out on thousands! People that are successful in life take risks and have no doubts! and that is about 20% of the population. If you do not take any risks , yes you are very safe, but everything will stay the same for you in life. Good luck.
