Is investing in the bankroll of a dice site (like Just-Dice) worth it?
If I left 0.1 BTC in there overnight, what should I expect to have when I wake up the next morning?
I believe returns in the biggest ever dice site, just-dice, as it still was running on bitcoins, had annual returns of around 11-12 percent. Other dice sites were worse at that time.
I dont have an overview about the actual returns. Though you should not think that investing for one day will get you a clear view. You need to have it parked for some time since the returns vary very much each day.
Consider every investment a risk. If you give your coins in the hands of others, you have lost them at this moment. If youre lucky you will get them back.
