Satoshi Nakamoto is supposed to own 1.000.000 bitcoins on a thousands of wallets, and most of them are untouched since early blocks. This stake can potentially flood the market, so miners could probably be interested in banning them.
So, is it possible to create a soft fork (protocol update, approved by most of hashing power), that will deny any future transaction with early block coins? It is not really fair, but miners are greed and they should probably approve it. Is it a possible scenario?
