I visited dbet.io as what I read in OP is really tempting. After a quick tour, I came out with few questions/suggestions if you don't mind:
It is not easy to select an event and place a bet using a smart phone. I had to scroll horizentally back and forth. There are mainly three columns in a single page so it would be better to make each column in a separate page.

When creating an account, you ask for name and username! I think username is enough since you are in favour of anonymity.

What if the country jurisdictions from where you are operating force you to implement KYC (it may happen any time). What are you going to do about it!
