Recently, I really enjoy following an account that started posting videos introducing the success stories of the old A-share speculators.

(The ones without real people showing their faces should be organized by the official Tao Guba, and do not represent personal authorization; however, even so, Tao Guba producing such content is at least much more reliable than other fly-by-night media, and historically, this aspect has indeed been much more rigorous.)

There are even real-life interview types, such as the ones I came across from Asking, which have a higher information density and are closer to the truth.

It may not directly help with trading in the crypto space, but many aspects of the "Dao" are interconnected.
Recommended to take a look.
