Is there any special reason why the majority suggests a casino that already has countless accusations of scam/extremely complicated KYC? When you add to that fact the OP wants to gamble for large amounts, doesn't anyone wonder what would happen if he starts winning significant and regular winnings?

@grandmaser97, my advice is to simply ask each casino if they allow such large stakes on sports betting - simply visit all online casinos that have sports betting, collect their contact e-mail addresses and send them all the same query.
