I am using betinasia for 2 years now and always received my withdrawals same day as requested. They have no reason to hold your funds cause such broker services have deals with all bookies and make a percentage on all bets placed through their broker accounts.
And if OP has used betfair in the past then I do not think he has a problem with kyc verification. As betfair sometimes also requests some id and POA verification
No crypto betting exchange can be compared with Betfair which is in some other league in comparison.
I agree with all your points and am not saying that this site is shady or anything. Am simply pointing out the fact that many crypto gamblers would find it tough to believe brokers even if they are completely legit.
Also, if op doesn't have any issues providing his KYC to this site, this is the best option. However, if he is reluctant to provide his KYC, Fairlay is the best option(Pinnacle odds and decent liquidity).
