Solid overview.
I would also add to check with different sources for their opinion i.e reddit etc. Now obviously there is a lot of shilling but I am talking about looking for other's opinion on the technical aspect of the project as not many people can grasp such information.
You mean checking for crypto influencers opinion?
I don't think there are many crypto influencers well-versed in the technical side of crypto, however on forums there are a lot.
Yeah i believe too, they understand more about other aspects, Medium is a good place to search for information, sometimes you find people doing technical and code audit to different projects.
