I like this idea, it's pretty good.

One suggestion, let there be a limit on how many times you can do this to people and how much can be given. A max of idk 160 plat would be the most you can give and you can only give it to one person each month, so you don't keep gifting that person plat. You can regift the plat either.

This is to control the plat purchases so STS can still make an amble amount of money.
