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?
Sia and Dent is a really good coins and both of them have cheap price on market and if you see the market both of them have good volume. But, as of now I choose ethereum for a long term because of their new upgrade.
