Youtube is the best place to watch videos so far in our time and I wouldn't call them courses but it's likely to be tutorial videos that teaches the viewers within the specific topic of their video. It's a free video sharing place so you can find them but not all of the videos that are posted there are true so please make sure that the video you are watching is legitimate teaching you the right course.
That is the problem with online tutorials. They are good for non specific things but if you want trading courses it is better to teach yourself or read a book. The fact that youtubers are nothing more than paid shills pumping their own altcoins makes it even more dangerous for newbies to follow them and give the video makers free ad revenue. Dont ever sell your view to these people who are nothing more than scum. But not all youtubers are like that, most of them are. So again you have to use your judgement to sieve off those publishers who are legitimate.Quote
You can also avail courses through udemy, coursera, etc but most are paid but IIRC, you can search for the free course just use your time to search.
Paid courses are blanket scams. You have heard of the suppoman scum havent you? Used to run paid courses and then give them out for free on his youtube channel. Those who paid 20 pounds for it were crying scam but got banned from his telegram channel. Nice scam if you ask me.
