For 4 hours, you’d get 24 PokéCoins if your Pokémon stays in the gym the whole time and then gets knocked out. That works out to 1 coin per 10 minutes, with a daily cap of 50 coins.

Quick math

  • 4 hours = 240 minutes.
  • 240 ÷ 10 = 24 coins.

Important detail

You only receive the coins when your Pokémon returns from the gym, not while it is still defending. If you already hit the daily 50-coin limit, you won’t get more that day.

Example

  • 4 hours in a gym = 24 coins.
  • 8 hours 20 minutes = 50 coins, which is the daily max.

TL;DR: 4 hours = 24 PokéCoins , assuming you haven’t hit the daily limit yet.
