Imagine asking someone how they do their own research about Bitcoin and crypto then they answer with Twitter.
Well.. DYOR is not an easy job. Imagine that most rely on what the officials say, and in most countries the central bank officials are still on the old "crypto is scam" or at least "crypto is too risky" page.
DYOR means reading all the sources you can, see what is the duplication and noise (both hugely present in social media, newspapers and also preached by officials).
DYOR means reading popular and unpopular opinions too.
I've learned over time that Bitcointalk covers this pretty good. There are shills here too, but also a lot of smart people. Of course, it takes time and patience and a new investor wannabe or even (omg) a new trader wannabe lack exactly patience.
Finding and filtering the duplication and the noise is very difficult and can too easily go wrong, because subjectivism also kicks in. And one may pick as "good" the parts that map better with their wishes and expectations, not with what is actually real. And, you know, the commercial looks better than the product. (PS. Interestingly, similar problem occurs with politics and voting too.)
