Getting to 15,000 Nanas might be harder than you think

In my previous post "Appnana beginners tip: get to 15000-nanas" I claimed it would take one 12 days to achieve the 15,000 Nanas milestone by just having the daily bonus.

Wrong! That was a mistake, because one needs to earn at least 4000
Nanas in points.
In the example account displayed on the right I started off with a default balance of 10,400. For 6 days I managed to get 400 Nanas in daily bonus. Then at day 7 it checked if I gathered 4000 Nanas via the 'Get Nanas' page offers. Or have 3 friends that enter my invitation code. Again, I need more friends! Add my code n6215050 and I will try to return the favor as much as I can!
