Your transaction fee is also 1 NXT which is changing to 0.1 NXT soon. That's great, but I'm never going to use NXT to trade because of that. So NXT can be the next PoS Peercoin, Blackcoin will be the next PoS BTC or PoS LTC.
Your never going to use NXT to trade because of what now?
NXT the next Peercoin and BC the next BTC??? LOL. No, you got that completely backwards. Blackcoin is the clone of Peercoin (actually, it's a clone of Novacoin I believe, which is a fork of Peercoin). NXT is the one written from scratch in Java. You noobs seriously need to start researching a little better before investing in these shitcoins, instead of just following the hype.
