I think it’s BC actually trying to launch a UK site. So they are now under a tighter leash.
Its the same with stake. They now have a UK site all be it a shitty one.
I think BC is winding things down and requesting KYC.
I would get out now and never look back.
Other alternative is golden bet casino. You have to verify,but they allow UK documents and you can deposit with cash rather than deal with crypto.
