The way the system works is that their token ALWAYS rises in value over time since you have to buy it when you "invest" and when you cash back out. The influx of new users constantly pushes the price up along with people reinvesting their earnings into their token. If you had simply bought BCC tokens last month and held them you would have made more than 100% return on investment by now, rather than the 30-40% they would have paid you in fiat if you had lent the trading bot those same tokens.

I have heard that they hold 50% of the tokens lent to them (for speculation) and the other half of the money they use to trade BTC and their own token. I honestly don't think they are using any trading bots just some experienced traders with a very large bankroll to play with. Even if they have a bad day trading they use the profits from their BCC markets to pay investors and they do a very small payout around 0.1% or less.

As long as people keep investing and new people are signing up their token will continue to rise sharply. The strength of Bitcoin has also bolstered their price since BCC is traded only for BTC.
