If you guys want to gamble, go to a place that has a low house edge, ETC primedice. This is the best way not to lose all your coins instantly 
I think they're really for different purposes. It's not possible to deposit coins into Freebitco.in. Hence any losses would be in the order of cents.
In fact, freebitco.in has been taking deposits for quite some time already. Just go to the "multiply BTC" page and you can get your deposit address after clicking the deposit button.
I don't think anyone would be silly enough to play here with deposits, but who knows?
