Actually, no. It's not normal for bitcoin betting sites to randomly ask for ID. And I've seen many people online confirm this. This is the ONLY bitcoin betting site that asks for KYC. And Of course I didn't provide full details in this comment because this thread isn't about sportsbet.io. It's about this legendary member that's a scammer. I'm simply advising people to be cautious of any website this guy promotes since he seems to be a scammer. And sportsbet.io seems to be very shady upon doing some research.
I used to bet a lot in the past and most of them DO tend to request it. But anyways, when you started betting at the website, you accepted their Terms and Conditions. And this is what it says there:
8.4 We reserve the right to use additional procedures and means to verify your identity when processing deposits into your Member Account.
If that's why you're calling them "scammers", then you are the wrong one in this case.
ANYWAYS... We are both off topic here. If you want to keep discussing this,
create your own thread.
P.S: Please stop with the cancer oversized font.
