Thanks everyone!
I realise that fundamental analysis is something totally different for the cryptospace, especially since it's still so young. So far I think the main parts to look for is in order of importance:
1. The team behind the coin, its reputation and how passionate they are about it (in answering questions from others, working on it).
2. The community behind the coin (Slack, Reddit, maybe also this site).
3. The whitepaper and how the team is able to get things done before each deadline.
Any comments on this, or suggestions to improve?
