Interesting list. From those I only know Betfair, Betdaq and the lat two. I'm curious on how you granted them their grade, and I found now info on your site on how it was done. It was a quick search though, so I will look into it again in the future, but maybe you could give us a heads start in this thread.
When I used betdaq, their only problem was liquidity, but I didn't expect them to be so far away from betfair, but I don't use them in a long time.
It's still quite a shame that we only have two exchanges accepting bitcoin to make bets, maybe this will change in the future.
yeah so far bitcoin exchanges aren't that active or that good , but you can still have access to betfair and use bitcoin
you can use asianconnect as a broker and ask them to create an account for you in orbit exchange or 9wickets , both are the asian version of betfair so you will see the same prices and the same volume ( they don't ask for KYC in case of bitcoin deposits and withdrawals but they exchange it to Euros )
waiting for a good pure bitcoin exchange may take a lot of time
