Although Pokemon Go is a free app, there are options of spending real world money like most free to play mobile games. You can spend real life money to buy the game’s currency, PokeCoins, which can be spent on buying several items like Egg Incubators, Incense, Lucky Eggs and PokeBalls.
Using PokeCoins in Pokemon Go could really accelerate your progress in the game, but it comes at a price, unless you are smart and use this method.
However, there is a simple way to save your hard earned money and get PokeCoins for free. All you need is to be above level 5 and have one of your Pokemon assigned to a gym.
First, you’ll need to raise the prestige level at a friendly gym if there currently isn’t room to add your Pokemon to it.
Secondly, you’ll need to defeat an enemy gym if it isn’t currently owned by your team.
When you totally defeat an enemy gym, you can leave one of your Pokemon in that gym to defend it. While your Pokemon defends a gym controlled by your team, you earn free daily PokeCoins for however many gyms your Pokemon are defending. You will keep earning PokeCoins without spending any money until the gym is under your team’s control.
In order to claim the rewarded PokeCoins, go to the top right corner of your ‘shop’ screen where you’ll find a shield. The number that appears on the shield is the number of gym you have Pokemon defending. Just tap on it and claim your PokeCoins. You will receive 10 PokeCoins for each gym you are defending at the time.
Remember, this process can only be done once every 20 hours or so. It is also wise to keep as many Pokemon defending the gyms as possible to earn more coins, so gather up some teammates and raise the gym’s level to make it even stronger.
