You need to make atleast a deposit to withdraw and there's a fee of 0.0001 each time you withdraw.
I don't think it's worth the effort.
I dont think there is an effort needed to claim the "faucet" on your site because since you dont put in captcha before clicking on the "faucet" image ,
all the faucet licker needs is a simple auto clicker software to claim the "faucet" from your sites.
Best thing to do is to put in 0.0002 minimum withdrawal with 0.0001 withdrawal fee to force the faucet licker to use the BTC to play on the sites rather than cashing it outI think OP already made this rule since he announced the site.
