I'm planning to build a game similar to spaceports, in which they reward the player based on the amount of token they hold, they don't need to buy any NFT item. they also have a limit per day reward which is about 2% daily.

My concern is what if after the player already earns 2% on a day and they send the token to another address and play the game again and again. How can I prevent that to happen?
