Surely this would depend on use. There's nothing essentially different about memecoins that would imply a distinct outcome from say bitcoin. Of all the ways you could use this test, differentiating between "memecoins" and "legitcoins" seems like the worst possible scenario: there isn't actually any qualitative difference to find in the first place. Hence, why this will eventually fall on courts to figure out.
I've never even heard of the term "app coin" before but surely it's just yet another crypto token with similar constraints and lack of obvious use.
