A theme topic, whatever often talked about on this forum, is the $5 hammer attack.
Many people suggest to keep your bitcoin holdings secret, thus preserving the anonymity of bitcoin to a certain degree.
But then you get sportsbooks asking for photos and passports, and god only knows what else.
If a sportsbook wants all this, I respectly suggest they change to fiat.
Basically you would have also let us know the platform that requested such information from you as a sportsbook. For me I wouldn't risk my life and privacy for just such dollars, even a thousands dollars doesn't worth my privacy. Although some gambler can give out their privacy for free but for me, never will I give them out.
