It's really hard to keep up with the cryptocurrency development even for a programmer. Every coin is trying to introduce a lot of new terms to show you how innovative it is. But in many cases it turns out to be just another vaporware. And at the end of the day you see that you've waisted your time for nothing.
it becomes easier over time to recognize shitty projects and not waste your time even looking at them. and you don't have to go through their codes to find that out! there are enough signs in their announcement and the general information you can easily find that can tell you that.
How many books did you read / how many courses did you complete before you started investing in Bitcoin? Can you honestly say: do you really have the time to keep up with the crypto world or at some point you just started to believe in tech instead of trying to grasp every single crypto feature?
you don't need to read a book or have any understanding of the "technology" behind bitcoin to start investing in it. would you also read books on understanding the technology that Apple is using in its product before buying the shares of their company? so why treat bitcoin any differently?
