Why not send your Bitcoins to them since the project is for you? If you are due any returns but do not receive them then who will you tell and who will you complain to?
This is not a project or a business it is basically a scam unless it conforms to basic website norms.
We've been in business for nearly 5 years and earned a reputation for being honest. That means much more to people who understand what Bitcoin is about than pandering to the demands of authoritarian governments. If you want to play at a site that is liable to pull full KYC on you if you have a big win then go ahead, but our customers value the fact that we don't do that and we always pay out.
