Don't want to test waters on random sites just to try the bankroll investments.
Yeah, don't do that. Invest only to casinos that has built their reputation in the community just like bustadice.
though I'm not sure how they're doing recently and even whether or not the site still allows you to invest into the bankroll.
I think they are still allowing it because it's on their faq.
