Investing in a gambling site is not really recommended in my opinion. Investing your money on gambling sites is very risky, because you might lose your money, and you won't even see it coming. There are dark secrets behind investments on every gambling sites, especially if you are not familiar on a certain gambling site you want to invest your money because you've been carried away because of the hype.
Is there any investment that is not risky? Surely there is no guarantee investment because all investment are risky. But I wonder what do you mean by dark secret on investment in gambling site?
and the word "Investment" has a lot of meaning, by depositing your money in a gambling site just for you to be able to play is already an investment, and also the investment that you will just deposit your money and you'll just passively earn money from it(that I've mentioned earlier) it is like you are investing in some HYIP sites.
If we stick into the main discussion, investment in gambling site is by investing your money on the house's bankroll. If you say that by playing your deposit is an investment than I can say that it is wrong, playing your deposited money on a casino is not investment but gambling.
