That's just the EMC cold wallet.
Estimates for BFL total wallets are 10,000 to 50,000 BTC.
Up until the judge ordered this, no one was expecting a forced sell event of any kind. That it's going to be done orderly has no meaning. Everyone will want to get their sell orders in first.
What are these estimates based upon? I understand BFL has always converted BTC from product sales to dollars. Do estimates assume differently, or do estimates assume that they mined 10-50k bitcoins and held them?
Traced BFL related blockchain payments, a lot of speculation about this in the hardware thread. It's way more than just the EMC cold wallet. The "$1M pre-order" BTC hasn't even moved since that press release.
