Ask HN: Learn about Finance and Cryptocurrencies

Lately I have been looking at Cryptocurrencies, wondering if I should invest into some.

Now the thing is, I barely know anything about finance. I am wondering, if there are any good sources explaining the fundamentals of both finance/trading and cryptocurrencies.

I am in no way looking for a way to get rich quick. I am willing to invest time and effort into learning about these things.

Any recommendations are welcome.
