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?
Sometimes good products are not necessarily good for the long-term future. The most important thing is the number of people who know about Sia products and whether they want to use it. That officially brings revenue to Sia.
There are a lot of good products developed at the blockchain, but most are not very well supported because the crypto market is quite small to promote their products.
