If his plan is what you think it is (and I have no idea if thats true or not) then he has already failed. He tried to push the price down last Friday. The combination of Friday (no fiat deposits), a dump on the market, closing the "ponzi like" business without warning, not paying out anybody, and being vague and noncommitable wasn't able to keep prices below $10.00. To payout the "interest" owed he would need to not only have sold off all 500K above $15 but would now need to buy the somewhere south of $8. It didn't happen and the market depth is growing. It won't happen.
Trying to manipulate the market to out manipulate a manipulator is just silly. Once again I don't know if that IS his game plan (sell high, spook the market and rebuy low to repay investors with devalued coins) but if it is there is no need to risk anything. He already failed. Let me burn off the rest of his investors funds trying to force it lower and just buy the dips.
Almost as silly as offering 7%/week I guess
I get your point tough. Nobody knows how much he has left, but the market is getting more resilient to his tactics. Therefore it is becoming less likely that his plan, if it is what I think it is, will work out.
What bothers me still is that one unpredictable person has that many coins.
