The purpose of fundamental analysis is to guide the trader to the "fair" price of an asset. This is a relative value that gives an understanding of where, at what levels it makes sense to buy and where it makes sense to sell.

Fundamental analysis includes information such as: 

the basic faces of the company, 
background, 
the tokenomics of the project, 
what exchanges it's traded on, 
whether it has real value,
 what are the real-world applications, 
extent of social media community and activity, 
affiliated individuals and companies, etc. 
You can start studying information about any crypto project with cryptocurrency aggregators: coingecko, coinmarketcap, messari, cryptorank. If the project is not represented on these aggregators, it is a strong argument in favor of the fact that it is not worth attention.
