All those ones are just what you need in either buying into such markets or holding. Just like you have stated, what is important is to get in details what actually makes the product valuable so you just do not end up bag holding shit coins and as long as you can sort that out, based on the team and product availability, it would help a lot.
OP must do some research online. I started investing in altcoin based on some of the articles that I saw online. Anyone will see so many of them, and can use that to filter out most of the coins or tokens common among most of them and increase your research further on them. As long as you are able to use this, get an idea of the product and what you are investing in as well as who you are investing in, which in this case are the team members, then you will be smart in your decision making.
