I also agree the NXT market is doing rather well, for a new coin.
I agree Nxt is staying consistently above USD 500,000 trade volume and being only a month old.
Only 4 other coins are higher....and they have been at it for a long time.
This is because, unlike nearly all other alt coins, NXT actually has some new ideas behind it, but the ideas are not small, they are huge disruptive ideas, similar to how disruptive bitcoin was.
Firstly, NXT is set to become the first open exchange platform--- OpenSource, decentralised NYSE. Think about those trade volumes. Think about the fees you can mine. This is a huge idea! Participants from around the world can issue stocks, bonds, smart property and digital assets (e.g. Gold, USD, GBP, EUR), without limitations. This will spur a huge business ecosystem centred around NXT, with NXT as the base currency.
At only 5 cents each (or whatever it is), NXT is great value in my opinion.
Secondly, NXT is a completely new, clean implementation with colored coins. Other colored coin implementations try to build on top if bitcoin, which is a highly nasty and cumbersome business, which limits a lot of the functionality. Moreover, it makes the implementations really difficult and hard to get to market. NXT will be the first to market because it does not try to build around bitcoin, but rather creates a clean and simple foundation to build on.
Thirdly, BTC uses something like 100,000 mega watt hours. To put that in perspective, Indian Point, which powers parts of NY, outputs something like 1,000 mega watt.
Despite its genius aspects, Bitcoin uses brain-dead (outdated) algorithms, which ignore energy efficiency and the environment. NXT solves this problem, by being highly energy efficient. In principle mining NXT uses very little power, probably as little as any other application running on your desktop. Contrast this with BTC, which requires special cooling hardware and power supplies.
Food for thought... technology forecasting maybe even.
