Site is new...owner is the same of skybtc, coinbooster, dreambtc, etc.

They will stay for some days and then stop paying like always because:
1)they are the usual scammers;
2)rates are unsustainable.

Their aim is to get a lot of traffic while the rates are low/normal and then stop paying/drastically change rates while earning from ads' views/clicks.

I will still use it but don't hope too much about it guys.

edit.
