i'm so sad that i have sold my minex below than the ICO price. at this time minex price has been breakout. i'm so stupid

I'm assuming you sold it $1 right after it gets listed on livecoin? And as i'm reading the laat pages there is somebody calling it a ponzi scheme because of parking rates i think he don'r read the whitepaper
You dont need to read a whitepaper to see a ponzi scheme. Every investment fraud will have great explanations for why THEY are not a fraud. For why THEY are legit. For why you should invest with them.
In any case they are giving out 80% of coins for free a year (even more weekly, and monthly), that ALONE is the perfect example of a ponzi scheme. No matter what smart explanations they come up in the whitepaper.
I am not saying Minexcoin IS a fraud. I actually find the team seem like nice people, and it could also be a very well thought out real business, with a great working bank, exchange and what other products they start bringing. The market seems to like it so far considering the rise of the price, so i would say all is good
The problems would probably start happening only in 5-10 years when they run out of printed coins to pay out (i know they pay less in 2nd year etc.)
