You're going to get caught. Then what?
The only way to do projects like this is to do it free, without receiving any substantial amount of money. I'm probably going to do an ICO, but it's solely to cover my own dev costs. The token won't have any utility. I won't have "investors" in the sense that people are expecting a >10x return. They're only "investing" in the vision and the people, not monetary returns.
You can't just take untraceable money for making a prostitution app and then expect the world to be ok with what you're doing. Heck, people will hate me for my project if it goes anywhere and the only thing that will save me (hopefully) is that I didn't try to turn a profit while doing it.
Raising money and trying to build out a huge team while skirting the law so flagrantly is a pipe dream and it makes me question your motives.
