That is a problem offering two possibilities, neither of which is practically acceptable.
1. Do nothing (network works ... that's cool / trading that's cool ... rather large premine that may or may not be in the hands of OP) ... again my best guess sold off long AGO.
OR
2. Fork, reward active participants. But need to get the exchange on board and get all legit holders to post addies. In that case sucks to not be reading this such popular thread.
Is there a list of those that received to initial disbursements?
