OTOH, pre -ground coffee oxidizes(?) Much faster than whole bean due to massively increased surface area. So it will get less bitter over time in part because there will end up being less caffeine. I guess if your grinder is sufficiently cheap it’s kind of a damned if you do/damned if you don’t type of situation.
If you buy whole bean, see if you can have a coffee shop grind it for you, they will have better grinders = less bitter cups out of the same beans

Yeah pre-ground isn’t ideal, but I know from the OP’s past posts that they don’t have much money so I wanted to suggest a free option.
