The bottom line is that as an investor, you don't really need to know the nitty-gritty stuffs about programming or coding. You just need to put your focus on what the project is about and their value proposition and don't worry much about the technical know-how except you're planning on deeply utilizing / utilizing their platform to build something. I used to be a huge fan of reading the whitepaper of different projects until I realized that it often don't ends up as expected (majority of the stuffs written there don't get implemented.
