The distinction isn't meaningless, it's actually vitally important. The thing is, we've been here before, hundreds if not thousands of times, with the stock market and other speculative bubbles. Once a big enough entity decides to cut their losses and bail with whatever they can get, all that "value" disappears and there's no inherent value of the asset itself to fall back on. So it has been with other crypto crashes in the past few years.

Granted, this is generally true of fiat as well, we just have a lot more people and hopefully some safeguards and, vitally, an active economy holding up that value.
