A couple of years ago you could easily get 100 green packs per day watching adds.
But people complained that it was too much.. yes they really did do that
hmm, not exactly like that.
100 greens could farm managers from UK, USA and few other European countries.
Most of the others had 5-10 or zero vids.
So it was a bit of unfair.
Now in majority of countries you can farm daily 25 greens.
