You bet on a two day old betting site that used anonymous registration?

Sorry, but some tips for the future:

Whois is your friend. 

Hidden registrations are great for personal websites but suspicious for businesses and twice as suspicious for BTC.

Time of registration.  For BTC sites you want at least 2011, anything less you gotta do more research.  Do research anyway if older than 2011.

You want a real name too.  You want to see old technical questions they ask from before the days of BTC.  You do not want to see someone who figured out a clever way to trade in WoW, a felon, or perhaps a club DJ.

You would want to see someone who had past experience with a fiat money gambling site.

Sometimes the enthusiasm of BTC advocates makes them vulnerable to the predations of scam artists.  So just look and look again.  Learn to research anyplace that you are trusting your money to for at least an hour.  A real investment should be researched for at least a working day or more.
