The first item I bought with SATs was a book for 500 SATs titled "WE INVENTED BITCOIN" which was very interesting to me, it was an educational purchase and I do not regret it. Many people use their SATs for purchases of necessary items not related to Bitcoin and that is part of the Circular Economy. In my case I am in favor of it, but also of buying elements associated with Bitcoin such as: paying for courses on Bitcoin, supporting educational projects about Bitcoin, Hardware Wallet to increase the security of our funds. In the long term, that investment in our education and security is smart and returns.
