So it seems...

WCX is supposed to be a new low-cost crypto-currency comming up. If you register now, you can get 50 WCX for free. They also have a referral system:

When a friend signs up using your unique link, you get 50 WCXT + 5% of the WCXT they buy, and they get an extra 15% bonus when they buy WCXT.

I only found this thanks to this post. Please give @pandorasbox some love and/or use his link.

In case you feel adventurous and want to use my referral link:

EDIT: I highly recommend NOT to pay actual money for those tokens. Use some throw-away email-address and a password you do not use anywhere else and only do it to get the free tokens. If they ever turn out to be worth something, good for you. If not, you did not lose anything. See also @tomshwom's comment. I apologize for not stating this more clearly in the original post.

Because it is always possible that such sites are part of some kind of scam, make sure to use a password you do not use anywhere else when registering.

Keep in mind that at the moment, there does not seem to be anything you can do with those tokens. Owners of WCX will have to wait until (if ever) this currency is traded on some exchange.
