I always advice others to read terms page carefully but to be honest when I join a casino or sportbook to check the site or even to play seriously, most of the time I do not give a full read of their terms. My main concerns are KYC related terms so I try to use my browser, search with KYC and AML keywords and if I see all looks convincing to me then I proceed.

By the way about KYC and things sportbet.one about page is enough for you to read if you do not want to go with long texts from their privacy policy page.
