First because betfair has a high variety of sports and LIVE events.
Second because you use betdaq when you could use betmate and benefit from a better commission.
as for payments received to moneybookers from betfair, they always pay me after waiting 12h, been paid this weekend within that time.
(they now delay every payment for 12h because of some poker players that stiffed them during the night, so now they double check every withdrawals made)
but they always pay me, during the day or night, weekends or holidays after that 12h wait.
Betsson and paddypower are the two quickest paying books out there (even quicker than pinnacle) - I've had sub 10 minute moneybookers withdrawals from both. Paddy once paid me a grand (approx $1900 US) in two minutes.....
Also quick (< 8 hours) are betinternet, stanjames, goldvictory, nordicbet, bet365 and ladbrokes.
Shame more places don't follow their example, it really helps with your confidence in a book's liquidity.
