Anyway so far I have these guys below any others that I'm missing.

Casinos
Betking

Money pot
I think if you want make investment in lending you can try loanbase and btcjam, they are place for make investment in lending business and about casinos i am not sure making investment in gambling. Because as we know gambling is just for fun except you have website gambling, but it is just my opinion.
