Why would you even store it as stable coins? If you weren't going to buy any crypto's and would only buy it, later on, might as well buy it straight later on as crypto, instead of buying stable coins right now. Besides, if the governing body of the said stable coins were to suddenly have an issue crop up, say, legal issues, you're money would basically be frozen there and then, and I doubt you'd be able to retrieve it successfully. Here's the thing, just hold it as Fiat if you aren't going to buy crypto.

Additionally, is there even a reason for hodling stable coins? Crypto, yes, for the future because they think of it as an investment so hodling it is completely understandable, but stable coins? Just buy some if you need it if you don't just let it sit as regular ol dollar.
