What are good technical books about Bitcoin and Ethereum?
"Mastering Bitcoin 2e"?
"Mastering Ethereum"?
Best option is videos only books and article would not be a fine to check all the aspects of crypto usage. I am still reading many thing in Youtube videos and sometime uses reddit forum too.
I suggest you to check the rise and rise of bitcoin in Youtube or some documentary videos also will help you get the proper knowledge to understand it.
