Same problem for me.. I have a balance of 0.09 so there should be no captcha but since yesterday the captcha appeared. I heavily use automated claims, never play multiply btc.. Probably they are taking measures for people like us

EDIT : Problem solved! now I'm back to no capcha, was probably a temporary error

Hi bitnux i really like your idea and i would like to be your referral but i already have an account. How can i delete my account? Or i just have make a new one and stop claiming from the old one? (I don't want to be banned for multiaccount  )
