That's because there has been a hell of a lot development and implementation since the initial creation of the block. It's called "capital appreciation," or "sweat equity," and it means that the value of the product is increasing because it is becoming a more robust product through the efforts of developers, who are augmenting the functionality, as well as marketers, and various other support people and mechanisms.
1) Has it really so much increased, that 1 BTC invested ~3 months ago is worth almost 3000 now on current market rates?
2) If yes, then I don't see a reason why a NXT "litecoin", being developed by a separate team putting it's own "sweat equity", and distributed however way the team wants, can't reach at least 3%-5% of NXT value.
