A few reasons why it is soaring :

1/ Business + crypto = real $, real value, can be bought by microsoft, dropbox, etc when they need to enter the cryptogame.
2/ Angel investor invested in
3/ No miner, no dump
4/ No Whale because they miss it, no manipulation, no shakeout, etc...The price was so cheap that "normal" people could buy. Impossible to buy 10 BTC ore more now.
5/ Working product - before ICO
6/ ICO with escrow
7/ Innovative. First movers make insane gains (DRK, NxT...)
8/ Proof of DEV, by coinsource and others. No scam.
9/ Profit-sharing with investors with 10K
10/ Anonymous features
