how will you delete other alts with your 50% premine?
he explained it.
imagine trying to delete bitcoin
1mill deletecoins will be worth 21mill bitcoins (1 delete = 0.0476191btc)
he then swaps the coins at that constant rate with bitcoin users until he owns all the btc...
i presume he then simply sends the btc to a random address that he or anyone doesnt have a privkey for.
please note this is for the worthless altcoins.. i only used bitcoin as an example, for numeric purposes
In reality , this will never work.
