If people buy Bitcoin on an exchange and leave it there...
And they never interact 'on-chain' they just want others "to buy" and "pump their bags"
Because they're "getting ready" for a "crypto" run and they've never actually made a Bitcoin transaction... or used it and they're not interested in that anyways...

I'm once again asking: What do you call someone who goes to the supermarket when hungry, buys food and leaves it right there in the supermarket without taking it home or eating it?
