Literacy can mean tons of things. If it's the most basic meaning, that is, inability to read and write, then Bitcoin is definitely not the top priority because reading and writing are much more important, and without them, it will also be very hard to use Bitcoin. If it's digital and economic literacy, I think Bitcoin can be a part of obtaining those kinds of literacy, but there are other important things here about passwords, knowing how to use different programs, how to navigate the online world, how to avoid financial scams, etc. So, to a digitally illiterate person, Bitcoin is inaccessible, and to an economically illiterate person, Bitcoin can be very risky, along with crypto-related scams.
