Main thing for me that I look for is a good community behind a coin that is important as well as the dev team being active and providing updates. Nothing worse than investing in a coin and having zero updates even if the updates are minimal they should update at least. Even if updates are bad those should be posted as well, the only time devs don't really post is when they are leaving and scamming you and regardless of whether you are doing that at the moment people will begin to think that you are scamming them. This is human nature those two traits are what I look for most and I know it doesn't have anything to do with tech but that is what I look for in a coin beyond specs. Anybody can have good specs the others are harder to come by and I appreciate them when I find them in a coin.
