Its a scam. They want you to deposit $100 to verify. Then you need to deposit even more just to withdraw any "winnings" you have, which im sure will be alot. To withdraw just $100 from "winnings" they want another $200. They say it's to confirm your wallet address, that you own it. You have already made the deposit through crypto wallet therefore its just wanting more and more. Its a scam, stay away. They can keep my $200 as long as it saves one person from getting scammed too
