If you hadn't earned anything through the side but worked for it day in and out I wouldn't want to bet on your integrity of not touching funds either to earn at least some interest for part of the user funds. So, please member of this "community" - don't pretend like any of you guys who possibly stealing electricity or misusing your company's resources that it would never have crossed your minds to earn interest or short btc. You are all experienced traders and prudent little angels, I'm sure. At the time, shorting wasn't outrageous but something anyone did who halfway followed Btc prices.
I never would. I'd be much too afraid of losing more than I could repay. There is NO safe investment in the BTC world. If I owe debts in BTC (which, if I am holding on to users funds, I essentially would be), then I keep that BTC safe and don't touch it, play with it, manipulate it, or "invest" it in any way shape or form. That is my responsibility on behalf of the users, whether I am getting paid for it or not.
I am sorry to hear that you sell your integrity for so low a price.
