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.)
There's only one word to explain your statement :
IGNORANCE. That is why the whitepaper is a must read for everyone. You don't understand it because you don't read it. And in the first place, MNX is not offering that for free. It changes everytime with it's algorithm. Your last statement too is pure
IGNORANCE. You don't even know that every March of the year the yearly inflation is revised? Makes you the MR.
Know-it-all without any deep knowledge about what you were talking about.
