I am trying to make a betting game where users can deposit USDC and play games when they win, the online gets updated and they can withdraw any time and when they lose, the program can take the money to PDA, but when I tried making this, I was unable to assign a away for my program to freeze that much deposited amount as well as have authority to transfer the token out without user signing it and I asked it gave me two complex things. One was a user had SPLUSDC. Then we could assign ourselves as the freeze authority while user is the owner as well as close account which will enable the user to revoke a delegation when we said the amount of depositfor delegation and second if it was to 2022, then we could add permanent delicate extension, is there any other much efficient way to do this?

That way you have control over the assets and the user's don't need to sign.
