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.
I'm not going to trade a currency that has ridiculous transaction fees like NXT. Look at NXT transaction volume on exchanges, it's terrible for having such a high market cap. So will all those things you describe require me to send NXT? Because eventually I'll lose my entire stash sending NXT back and forth.
I'm saying I see NXT as the PoS Peercoin. The PoS altcoin that tries to be a niche and does well. But I see everyone using BC for general transaction. Can an altcoin be great because of it's simplicity? We're about to find out.
I've got some NXT because I was curious, not enough for it to be considered an investment. Now I've got some I can only really see one use for it, and it may be important. The problem with all other cryptos is that you are NEVER going to read out your address, or transcribe an address, over the phone, with NXT though you can. But the client would have to become much better packaged to reach this niche. Also I don't see 'everyone' using BC for general transactions just because it is the 'hot' coin for quick trades now.
