Peercoin seems like it overcomes the 51% problem bitcoin has, so is peercoin the longterm winner once mining ends?
I mean once all bitcoin have been mined out.. no reason for miners to keep all that hardware going, the NSA could take over the entire network and be in sole control of all transactions.
The reason Bitcoin has 90% percent of the market cap and other Alt Coins 10%, is due to network effect. For an AltCoin to take over Bitcoin, the innovation or advantage has to be so big to overcome the network effect.
On the otherside of the coin, AltCoins are lower in price, so the possibility of higher reward is greater as well.
