It is 100% scam .Dont trust .
Just like other scam sites Wox.ltd is also one of them. It says that it provides 20% after 24 hour which is not real. In fact such sites do not exists . They come into existence just for earning money. Only some of its users are getting payment (about 3% of total users).
It is using virtual location to prevent tracking and providing fake certificate of approval.
Scam sites rarely provide payment to some users only to prove themselves as legit. However some of the people are posting that it pays . But the fact is that they are also not getting payment so they are trying to increase their referals to get payment by encouraging others to join it.
I suggest you not to trust such posts of forum without proper research. It will be better if you search another legit site instead of investing in this scam.
