So you don't wish someone had told you that you need to learn everything about the market and the industry first before you attempt to make money out of it? Because you didn't mention that in your points, when it's one of the most basic things one needs to do as a beginner. How can you expect yourself to become a good trader if you don't even know everything about trading itself? You don't just need to know how you can use an exchange, how you can place a buying or selling order, and how you can deposit and withdraw funds in your exchange account, but you need to know everything.

Think of it this way, you want to take a test, a test where you will be answering questions based on a book you must have read before taking the test. Now, you appear for the test, but you only read the first chapter of the book, and didn't read the rest, but the questions in the test are from all chapters of the book. How many right answers do you think you can get? Only a few, right? Now imagine if you had read the whole book, wouldn't that make the test easier for you?

That's how trading is for you.
