Good luck cashing that out without crashing the market. Somebody pointed out, just a few days ago, that a $10k sell-off recently scrubbed 25% off BCN/USD. A 400,000BCN sell-off would almost certainly drop it to pennies.
edit: Ah, I see your point. You said "redeem back to cash". Yes, that probably wouldn't work in an economy only worth a few million :)
