Hi!
Are there any besides Nitrogen? It is so hard to find trustworthy sportsbook who accepts bitcoin(or BCH would be best) and has eSports in theirs offer. I have been using Betcoin and mBitcasino but they seem bit fishy. Even site like fairlay which is crypto only has KYC procedure... and i don't get it.
I played on sportbet.io , they accept BTC and as far as i played last time( more than 8 months ago) they didn't take KYC for Payouts.
So you can give it a check and can ask their live support about their any changes in the withdrawal process or not.
You can moreover bet on stake.com which also has sports betting options. They too do not take KYC for processing the winnings.
But it's always better to ask the support team at a particular site and enquire about all the details before depositing a single penny.
