In my opinion, the most important aspect to look at before investing in a crypto project is about how the project will change the crypto world, that's the reason why projects that bring new systems or are in the hype of new systems will increase in price over time. As we recently learned about Metaverse, you can see that in the past Decentraland (MANA) was very undervalued, and with the new system coming (Metaverse) it is a breath of fresh air for projects related to Metaverse.
For reading material about the crypto world, I strongly encourage you to always look at the news on Cointelegraph, because they are always updated.
A vesting schedule is a schedule where other tokens that are not in circulation will be circulated to token buyers (usually to seed investors and private investors), I personally think that a good token is a token that has a vesting schedule that is not too fast, because it is very clear that, the sooner tokens increase, the scarcity will also decrease.
