They also represent the in-game currency that you buy with real money.
You will be able to go into the Shop window once every 21 hours and cash in.
Based on how many Pokemon you have in a gym, you will get an equal number of Pokecoins.
The button to seize it is in the upper right hand corner of your Shop window.
c’mon note that there is no confirmation screen.
It is for 21 hours once you press it.
You cannot press the button when you have zero gyms.
For every Pokemon you have in a gym, you get 10 coins and 500 Stardust.
If you have five Pokemon in five gyms, you will earn 50 coins and 2500 Stardust.
you might have an infinite number of Pokemon in an unlimited number of Pokemon gyms.
However, the cash in maxes out at 10.
This means you could earn up to 100 Pokecoins and 5000 Stardust every 21 hours.
c’mon note that Pokecoins are a valuable resource and they are rare and expensive too.
Therefore, ensure that you choose to spend them wisely.
