I don't know about that.
A lot of things could be read in a book and you can't actually read them online unless you bought them as an ebook. Internet and Books could be our resource of knowledge to trade.
Exactly. It's just plain wrong to say that it's not worth it to read trading related books. To be successful in anything, first you have to know fundamentals, and what's better way to learn those other than reading. Those who skip those basic steps and just rush into trading will learn soon enough that it ain't so easy to be successful, and that it takes a lot of time and effort, otherwise trading will be gambling and nothing more.
An average crypto investor is impatient, greedy and ignorant so I'm not surprised that some even think that educating themselves via books is a waste of time.
