It is clear, only to take money from people.
I'm sorry Sir but you don't explain how they are making money with that.
In all HYIP and pyramid schemes there are winners and losers.
If you sell at the best moment you win money, if you sell at the worst one you lose money.
So if Yobit didn't sell any of this coin, it didn't earn any money, it's only users like you who won money.
IDK there may be elements of organized crime here, maybe someone who knows the law better can explain.
If you think HYIP and pyramid schemes are "organized crime" why are you on a forum allowing them, then?
At least 2 sections here are dedicated to that
The Gambling section
Gambling and all "investments" that are so risky they might as well be gambling (HYIPs, pyramid schemes, etc.)
The Investor-based games section
Games where the main factor is whether or not new "investors" join the game. Also any Bitcoin-denominated investment product with an APY far above the reasonable market rate.
