I consider every aspect of a coin or token when considering it for my portfolio. That means looking into the graph, the team, the community, the product, and any underlying scam or fud claims that have been made. Another aspect of coins that can help figure out what is going on is the mining side of things. I am not really technical but if a coin is being mined heavily that generally means there is some interest there which is a positive sign, but it isn't a for sure sign. If all these aspects add up then I consider that coin which makes me choosy but the trade off is having more winners then.
