I always prefer to just purchase the phone outright and be done with it.
I've gone that way too recently and just bought my phone inadvance rather than paying off a tab. Granted, my phone wasn't the newest IPhone though. Still, it seems better to do it this way in the long run, if possible. It's cool that you showed the process of converting crypto to do so. I've never converted crypto to any sort of Fiat so I still don't know how to do it 😆
