The problem they had if they just left it in the dollar wallet was when the price fell due to the news, they would have to pay more BCC for the dollars. They probably would have run out of BCC and would have had no incentive to keep the token price up after that. They instead paid everyone at a fixed rate as it was better for the coin's future not to flood the market with too many. Remember these loans weren't meant to be refunded for many months.
After getting $13 million a day in the BitconnectX ICO, I doubt they would have bothered doing something for a couple of million and being easily found out on the blockchain.
This guy is a special kind of idiot.
He can post that they manipulated their market, explains they wouldn't have money to make good on their promise of giving people their USD back and then says they cared about the coin's future (while creating an even more dubious ICO for a 2nd coin - why create a new coin if you care about your old one? Oh that's right, to keep the old scam going longer).
If the guy isn't careful he too may get a subpoena since it seems like he knows a lot about the inner workings of Bitconnect.
