Enwy is illegal because it uses a ponzi scheme or / and a matrix scheme to pay people. The use of this site is therefore totally discouraged.
As of today an gain amount of 0$ was reported by netbusinessrating members for 78 days but as we hope you know, this kind of bad site can close overnight without warning.
After taking a look at the website, it looks like a ponzi scheme. Reviews found upon a Google search didn't help their cause either. I'd would stay away from them.
