How often do you get $20 dollars in Adopt Me?

Excuse me, I'm curious about the Adopt Me game and its in-game economy. Could you please elaborate on how frequently players tend to acquire $20 dollars worth of in-game currency or items in Adopt Me? Is there a specific mechanism or set of tasks that typically lead to such an amount, or is it more of a gradual accumulation over time? Additionally, do you have any insights into how players can optimize their chances of obtaining such a sum efficiently? Thank you for your time and consideration.
