Odd`s are pretty much the same everywhere, as I know. I didn`t find any huge difference with odds on soccer, I mostly bet on that, maybe for some other sports odds variate. I support your point, why would we bother with sports book that asks for KYC, when there are many good crypto betting sites where we can bet on sports without any kind of KYC.
Like OP said, it`s a torture to take a pictures of yourself, ID and yourself, just ID, last utility bill, etc... I don`t like to do that, and I`m avoiding KYC whenever I can!
When I was a student I bet on football at the usual bookmakers, which were placed a lot in my city. As a rule, they are always asked to write the passport data in the ticket to receive the prize. It is clear that they need it for reporting.
But why it is necessary to network bookmakers I do not understand and do not want to provide them with their KYC data. I don't want them to sell them to anyone else.
This KYC thing was useless, and it seems that the people is getting exhausted with it. If this process continues to occur on all sportsbook, customers will decrease and will prefer to choose those other online gambling sites who doesn't require any personal data. Exposing you private information isn't safe for us, and possibly your personal information could possibly be exposed to illegal activities.
