I was planning to try for fun to invest in the bankroll but yes certainly risk does exists and even without risk their are no rewards. Will go through this in detail and let see if find it more exciting might end up becoming an investor in your site. At times even luck is very important beacuse moment you invest and somebody wins big you end up in a loss.
Yes big wagers is certainly a concern to investors. We have already plan to limit the max profit to less than 1% of the bankroll to protect investment, because we would like to provide a stable return of investment to all investors.
