The more you play the piggy bank, the better it is, but it is your decision to buy the piggy bank, if you buy it, it is fine and if there is no problem, you are not obliged to buy it, just ignore it.
Hi @ApacheWARrior as @Suzuka has said you don't have to purchase you can just ignore it. A tip I would give if you do plan on purchasing is wait until it reaches full =50 its much better value. Happy gaming 👍🙂💎
