Was planing to invest on a gambling site since they said its a gauranteed profit since the house can't lose but I'm still skeptical about it, i don't have much BTC so I have to make sure whether its going to be profitable for me. What possibilities could happen to the gambling site i wanted to invest into and how am i going to lose my investment in such a manner?
Two big issues:
-site being hacked
-site owner leaving with the coins
Appart from those two possibilities, you should be perfectly fine

True, the two biggest risks into investing dice-sites.
