it won't stop, because if site balance is too low to cover a payment, that investment lose, but the next one can be paid.

Think about this game like: I bet that after 100 hours, the site balance is going to be enough to pay me. But of course you can bet and lose.

I cannot affoard a giveaway right now, maybe in the future. But I am giving the chance to the users of this forum to be the first to invest!
