Yes, it seems to me that the main people who will vote will be motivated players who will be shown pop ups with free spins per vote on the main page of the casino. And also, I did not see many good casinos in the voting. I tried a lot of casinos, now I play Fairspin, I don’t know why they weren’t included in the nomination, this is a good casino on the blockchain
Maybe the OP hasn't made any deep research on all available blockchain casinos or the OP prefer to include only the well-known one even if they aren't that reputable in the community. I saw fairspin on ads and I guess that's how they promote their casino but haven't tried there, so do the OP maybe.
