Jake Paul says Dana White still owes him a million-dollar check for beating Ben Askren, but the Problem Child is once again proposing a friendly wager with the UFC honcho ... saying he's willing to put $5 MILLION on the line when he fights Anderson Silva.

"Dana White did not think I'd take this fight," Jake said minutes ago.
