I like that sportsbet has instant withdraws and since they pay the fee the Bitcoin always arrives fast
I dont know of any BTC casinos that really offer instant withdraws even sportsbet takes a minute or so
It is normal to have delays cause all transaction will undergo process even sportbet withdrawal, but having to much delay will never be good at all.
Delays will never give me a huge deal, the most important we are secured and we are playing in the right place(legit site).
