I received my WD in about an hour yesterday.
My account isn't huge (Production of 70409 at present) but I've never had any issues.
I am not saying that there are no issues with this site, purely that I have not experienced any.
I am also aware that it could be some form of Ponzi or similar (and the recent promotions have made me more than a little nervous) however, again I have no evidence of anything untoward, and, as a consequence I think it is fairer to say that this site is legit. This of course may change, but I hope it doesn't.
Finally, as with all things crypto only put in what you can afford to play with, and, potentially lose.
