I have been watching gambling streams but I never had an idea about some fake bets like this. If this is true, it is up to the agreement between the streamer and  roobet. Since roobet will gonna lend some dollars for the streamer to play with but 100 usd is her/his talent fee then I don't see anything wrong with it. It's just that I am kinda surprise that there are some tricks like these.

However, this kind of advertisement will attract more players to deposit to their webaite if they see they are able to win huge like that of stremear. The only question that I am confused with is that, what if the streamer won huge using that lent bank roll? Will they give him additional payment?
