Classifying something as a Ponzi scheme, usually involves outright fraud. ie someone is claiming that there is a huge pile of cash somewhere that doesn't actually exist.
There may be individuals committing fraud using bitcoin. And bitcoin may be a speculative asset bubble with very similar outcomes to a Ponzi scheme. But it isn't *technically* a Ponzi scheme.
