Yeah, they were productive just in one way - to make parts of system who collect money from investors - wallet ,Minexbank, Instabuy
They made OTC option only for buying MNX coins InstaBuy, but not InstaSell as OTC selling option. Money outflow is not allowed

Logically,bank should have both options, Buy and Sell ,as a tools for regulating supply and demand.
It is absolutely necessary if you want to regulate price of coins,like it was promised in whitelist.
Not making InstaSell option was a clear sign that whole project is one way trip.
How much time do you think they have before they use their exit strategy and dump everything?
