I agree that SHIFT might be a good short term investment, but it's a long shot to be a serious contender in 2-3 years IMHO. I don't like that there's very little information regarding the team on their website. Not too many of them, and no detail on their qualifications or experience.
Yeah, my main concern is lack of information about their team. And roadmap is only planned till Q3 2017.
Yes, you are right. Devs are working hard. I love 'em.
Q3 2017 - Phantom on mainnet - new website - roadmap - whitepaper.
Phantom is on testnet now. You can play with it.
