It's not a quick earning method!

1. Through http://goo.gl/ok4H0V
2. Through http://goo.gl/32bnRe
3. Register then start mining DOGE, every 3 days change to GHS & change again to DOGE
4. Repeat step 3 afterwards

No survey.. No task.. but Automated.. That's why this method is slower (the trick is you need to wait every 3 days)
