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. Bustabit not Bustadice.
Bustabit has alot more volume.
Was also confuse with this since Bustadice is popular in the forum due to their signature campaign.
I check their website now and they have 1% house edge as stated, personally I haven't played in this site though I have played crash game before.
@xxjumperxx have you invested in Bustabit?
Bustadice is a bad choice if you are going to invest there, the volume of investor and the bankroll itself is really big so you are just going to get a 0.001 or less fraction of the investment itself there. I Highly suggest that go to Yolodice since it's establish gambling platform and their bankroll investing is just newly open, so you are really gonna get a good deal there 
Based on the record of your investment, we can obviously tell. BTW, you are not planning to add new site now? like this Bustabit recommended by xxjumperxx .
