So I've recently coded a Bitcoin Gambling site (only one game - hi/lo). It works fine, provably fair, and all. I stil have to work on the frontend though (styling, responsive design, etc.). That won't take much time. I'm planning to get the site up and running. I have a few questions:

1. Legal aspects. Would I need a license?
2. What should be my pot/bank size to get it started?
3. Best practices for running a BTC Gambling site (any BTC casino owners answer this please).
4. Any tips you'd like to give me?

Thanks.
