well this sooner or later would happen. Those >5K MSC holder dragons will be wakening one by one if they see the price is going up madly. Still I believe dacoin's possible offer is caused by his integrity to push back the things to sanity again!
Holy crap, exactly how many have more than 5000 each?
You can get some information by exploring transactions for the month of August to excel format from blockchain.info (after showing confirmed only and received only), then sorting highest by lowest...but that just shows individual transactions...not total wallet balances. I'd be interested in seeing the latter.
However, going off of this raw transaction data... I'd guess somewhere between 14 and 18 folks have wallets with >5000 mastercoin (or at least this was the case at the closing of the window to contribute to the exodus address).
A more in depth wealth analysis would be great!! Things I'd love to see:
* Distribution of wealth (e.g. how skewed is it towards whales)
* Wallet balances of top 25 holders
