You must remember that BTC has had 5 years to grow. NXT has had 7 months and has made incredible growth but it is only 7 months. When I first heard of NXT I jumped on board immediately. I hadn't been that excited since first hearing of Bitcoin in June 2011. Back then there were no real venture capitalist investors, no angels, just people working their butts off to create the community and develop infrastructure. That is what NXT is doing right now. People believe in it far more than I've seen anyone believe in the alts. NXT isn't really an ALT ripoff coin anyway, all new code, second gen crypto.

I don't see NXT replacing BTC. I could see a future in which a couple cryptos co-exist. Visa, Mastercard, American Express.
