ah ok, then yeah, microsd

it's MUCH simpler than it sounds at first

I honestly once onboarded a boomer via zoom

* had never used bitcoin before:

* airgapped coldcard (microsd)

* connected his coldcard to sparrow

* receive corn from an exchange

* spend that bitcoin back to himself

it all took less than 1 hour

it SERIOUSLY is not that hard once you get your hands dirty
