I think this is the biggest attack vector in Bitcoin.  All those coins are one 6102 away from being easily seized by the Government.  

Then they fork the network and use their massive amount of coins to drive OG Bitcoin price down, causing market panic..... further driving OG Bitcoin down.  Next thing you know Bitcoin as we know it now is gone and govcoin is here.  

I think our best hope of resisting this is other countries sadly.  If Russia, China, etc. gets enough coins to stop their Fork attack that would be best case
