To avoid such scams you should invest your money only in trusted sites and those details you can find it easily from this forum if you spend some time here. Also, you shouldn't put all your money in single site but try to invest in few good sites then you're chances of making a profit from these investments will increase.
If someone wish to see the comparison of how most gambling sites is doing here in general then take alook at dicesites.com. you could see the wagered amount as well as the profit made daily and compare it with some other sites as well , so anyone could do their own research regarding which is the best sites to put their money in
But its a widely known fact that " anything that sounds too good is probably scam" so if some sites shows huge profit not always means that we should blindly invest there.
