I also cannot name casinos or other gambling sites that have automatically tuned it.
I am betting with Sportsbet.io and Betonline.ag, they proceed withdrawals without any fees between 10-30 minutes, despite my usual withdrawal is between 5 - 10 k EUR. I cannot say, if they proceed withdrawals automatically, but every time they finalize them in mentioned period of time. It is really cool to have Your winnings in own wallet so fast!
I personally also think that a payout should reach a player quickly. It will matter what kind of player you are, if you have a verified account and passed the KYC, things will go faster than someone who creates an account for the first time and wants to pay out. Sportsbet.io and Betonline.ag do exist very long on this business already.
What I expect is that Adkinsbet will process withdrawals faster by the time, they just started so not a big deal, as long as you receive the funds.
my both accounts at Sportsbet.io and Betonline.ag are not verified by KYC check, they exist from a long time, just for the info.
