Some new entrants in cryptocurrency trading do trade blindly on coins without doing their research on coins before investing, majority invest base on FUD or a pump group which are not realiable.
The following are some of the factors to consider before investing in coins base on long terms investment:
On-going Projects
Community Hype
Market sentiments
Future projects
Social media reach
There's really a lot of pump groups here in our industry and if you are going to follow them blindly you are going to lose a lot and so it's very important that you have a good criteria like you have there in your post, you forgot to mention the team behind them are they real, so many fake profile on some ICO.
