Nothing created by MLM companies, especially altcoin ones, should be listed on stock exchanges (or anything for that matter). They are just, in this case, a complicated way to phrase a Ponzi scheme and these will never turn out well, they'll just collapse after a while. Don't put your money in. If you're talking about altcoin exchanges, the same pretty much applies.
We have seen examples of this number. Many MLM companies are trying to trick people using crypto currency.
All these companies are ponzi systems. Therefore, altcoins issued by such companies should not be listed on the commercial sites.
Let the people in your neighborhood know about this.
