I did not see the survey on the site you linked - where did you post it?
PlexCoin is certainly an extraordinary phenomenon to me, the way it will be launched, the phased rollout, the promise of massive returns, and the MLM element where you can get people under you buying the coins. It does seem very high risk and it seems like virtually anything could happen to the price between the time you buy it and when it actually trades on the open market. It's also launching at a time that could be rather volatile in the crypto market, only a few days after the Bitcoin soft fork. No one knows what's going to happen with the soft fork and people are already saying you should hold back from trading cryptos in the days following the soft fork. I don't know. I have never participated in one of these before. Are you going to buy in?
