There are a lot of websites where you can learn to trade, you can buy different books on ebay which all covers the aspects of trading and you can apply this knowledge in any trading are, i.e bitcoin and altcoins. You can register for an online or offline course which covers all the basics of trading and once you finish it you have learned all the basics in trading. If you want to learn skills free without spending money then only Youtube videos can help you, there are a lot of them on the subject you are asking.
I dont think so. I think all that guidance is general theory. You can find it in the investment book, sometimes the book brings more useful information. To become a real investor, you should have a course on investing. Do not regret the money for knowledge, it is very important.
