For a crypto beginner like me is the so-called whitepaper some I should count on when doing research? people are still talking about the whitepaper of crypto projects but few people said it doesn't matter.
If you are asking for this then I think that you're already doing something wrong.
Be careful because most projects (tokens, altcoins, whatever) don't live up their promises (some are scam, some become scam, some are just unlucky or bad projects) and you will be tempted to invest your money into those.
You may want to stick with Bitcoin until you understand (much!) better all those "offers".
