Bustabit is a good site to invest into also. Yes its not a dice site per se but it has loads of volume and players. It has a dillution fee but I think volume wise its hard to find a site like it.
OP had already remove his investment with Bustadice, I think he is only focus now on one site which is Yolodice, what he is doing not is he YOLO on this gambling site. Poster above you has a point, he cited that investing in one site alone is not a wise idea since anytime they could go away and take your money, but then, since we are investing here, we also take it as gambling so we can afford what we will lose.
