At the end it doesn't matter, I'm not selling it. It's just a simple PDF that I wrote, nothing more, nothing less. I don't expect anything from it, I don't plan to sell it, I'm not even crypto enthusiast or fan. I just wrote that while educating myself
Maybe you wrote some parts of it, but you didn't write the whole thing, and you didn't give credit to those whose information you used. On top of that, you are finding reasons why it shouldn't be done instead of doing the right thing. Plagiarism means copying someone else's work and pretending it's your own. The copying part isn't a problem. But pretending and saying "I wrote it" is.
We cannot consider sites such as coinbase.com/learn, Binance Learn, ByBit Learn, etc. to be sources of information and therefore not references for academic stuff.
Whatever sources you use, should be mentioned. That way, you have done your part.
