Minus the obvious BTC for the looong term win, I'm going long on:

(1) Sia
(2) Dent

Here's why:

(1) They're both really cheap right now
(2) They both seek to unsettle massive players in established markets. Sia is smashing cloud storage players and DENT is disrupting data strongholds in mobile
(3) They are already delivering fantastic products

What are you long on, and why?
