Is there a reliable source of information for learning about cryptocurrency? For example, I want to learn exactly what the technology behind it is, what each coin is supposed to be useful for, etc. I know I'll probably hear "read t he whitepaper!" but to me that sounds like a recipe for disaster, you can't judge the value of something based off of the promises the company itself makes, that's how brainlets get tricked into buying early access trash from developers who will dump the project 2 months after alpha. Google is of absolutely no help either in current year, you search for something and the first 3 pages are opinion pieces, blogs, or obvious scams.
Investatopia seems to be a good source of information and I've been learning things from there and lurking here on /biz/, but I'm not confident enough in my knowledge yet to start making good moves with my money. I want to escape the wage cages someday, so can you anons point me to decent places to learn about investing?
All I can find are indian blogs and boomers saying anything above a 3-6% annual ROI "isn't realistic".
