Good evening friends, I am selling my stars at over 90.
Best regards.

If they come from the store, you should have waited 56 days × 3 seasons before putting them up for auction, then you're taxed at 100%.
If it's gifts because you're level 1 I don't know

No, no gifts, no worries about taxes. It's a game

3 seasons the players would have aged too much so they would have lost too much value so it comes back to the same thing.

Okay, but 100% of the profits, and since you're going for zero, it looks like you're going to get zero.

they can sell gifts that don't come from the store
