If you're going to implement such or a similar value on your website, i ahve a simple request based on current problems on CSGL. Instead of basing the potential reward on the odds/numbers of the bets, you should base it on the betted value.
You can ofc still keep a certain amount of skins to get the money you need but basing the potential reward on the amount of bets makes no sense at all.

Just an extreme example:
50/50 odds, 50 people betted on each side.
Side a betted a overall value of 1000$, side B of 100.
Based on the amount of bets, everyone would get 1$ for 1$ -> Not possible if Side A wins. If Side B wins, you ofc make a lot of profit (900$)
Based on the value Side A would get 0.1$ for each betted $. Side B 10.

This is ofc exaggerated but it believe it shows the problem. As i said, your service won't be payed from nothing so it should be possible to keep a certain percentage. Yet, the potential rewards will be true and more accurate.
By doing so, you stay out of ♥♥♥♥♥♥♥♥♥♥ and people actually get what you promise them to get. They won't feel disappointed/scammed.

There are ofc disadvantages, especially if people want to bet a lot of money on underdogs. So another solution would be just not to show a potential reward at all. Or write a big, fat disclaimer which explains the situation so people won't be upset.
You just need to fix this problem, no matter how. Either trough clearly stating the situation and telling people (!) that its not based on the value of the bets but the amount of them or changing the system ^^

Opinions on this?
