Since I imagine that I am a little bit older than the average person in the forum I am not really comfortable with online courses when it comes to learning how to trade, if what you want to do is to watch the analysis of other people I agree that an online resource is better but when it comes to learning nothing surpass a few good books about the subject.
There is nothing actually bad when it comes to online educations resources, or trying to get a hold of some information on trades, it is what you do with them that matters most. There are actually some websites such as
https://tradingstrategyguides.com/blog/ ... investopedia where you can easily get some helpful information that can make you become a better trader, it is just your zeal and patience to learn that matters most of the time and how you are able to apply those information you get to see when you start trading.
For now, my trading resource is telegram. For note, i only follow channel token that i still hold. Because i can see when developers update their project early and make my decision what i will do with my token
I am also part of many telegram channels but what I do get from them is, just attempts to pump in group some unknown or utterly lower level trading assets. After seeing their trading calls, I went for analyzing those coins and found why they did recommend one particular coin. Basically, some people are trying to bait innocent traders through these types of channels, hence being careful is suggested.
