Whatever you invest in any gambling sites will be used as bankroll for that casino and whatever you may earn out of that investment depends upon the profit or loss site will make in future proportional to your investment size against total bankroll.
You invested 1BTC
Site have total bankroll of 100BTC
Site made 10BTC in profit in one month.
You will get 0.10BTC in profit with 1BTC investment in one month, after profit your new investment amount will be 1.10BTC
And your balance may also get deducted in same proportion if site loss 10BTC total in that month. So investing in gambling platform also have risk but that is quite lower than gambling. Return is very low while there is also risk of losing all you have invested.
You mean there are much chances to make money than loss .
Actually I was looking to invest about 0.4 btc but I am confused whether to invest or not .
I made the total earning of 0.4btc in three months , now I am thinking what happened when all goes loss ,according to your last line , Should I need to make invest or not any suggestion .
Today I got more numbers of bitcoin gambling investment sites , but confuse to select .
Here I need to choose between moneypot and bitvest .
edited : I don't found much profit looking to much low , if I invest 0.1 then I will get useless amount of bitcoin earning .
Don't get too confused by all that man, it's really easy!
You invest whatever you can and want. It gives you a share of the bankroll: your investment/total of bankroll
Then whenever the casino earn or lose money you earn or lose the percentage of the bankroll you have.
The idea is that with low investment you won't earn much but you also won't lose much.
The risk exists of course but the casino will win statistically. Investing in a casino is the same as gambling but instead of seeing a 1% House edge, you're the house so you're the one who have the 1% edge!
Hopes it clarifies your questions!
