Based on my research:
- Sportsbet
Same as here, I've found that SportsBet.io was the #1 Bitcoin sportsbook but I checked the review lately. Most of them gave 5 stars for its instant deposits and withdrawals. Without any confirmations, you can actually withdraw and deposit from the said platform.
60 seconds was the approximate time for the person to receive his withdrawal directly to the wallet.
I'll be sharing you the link of the reviews.
