Currently Binance isn't allowing new users to sign up, but if you use a referral link it will allow you to sign up. Check my signature below this post for a referral link to see it work
Heard about this a day or so ago and was able to help my friend sign up, thanks for sharing and helping others. I have a feeling that if they haven't already they'll soon close this off, it can't be hard to see when new users are signing up for them and then it's just a case of locating where that traffic is getting in.
