If this is required to stop bots that were somehow exploiting what you had before, that's cool. But... can you please turn down the difficulty a little? Tonight I have been trying for ten minutes to solve the recaptcha. Click all the cars... I AM clicking all the cars. Yet it marks me wrong. I give up for now. I hope it's less difficult tomorrow.
The balance needed to remove captcha is 2x your free roll winnings so it's possible you have won enough to need to deposit some more to get back to 2x.
The difficulty of reCapture is set by Google not Freebitco.in and it generally gets more difficult due to the number of requests from a specific IP address or browser. Also using an incognito window can help. Failing that if you don't do any for a while they get easier again.
