Learning from YouTube wastes a lot of time and irrelevant things come up but I got help in very short time from this forum and from the respected members of this forum to know about the things I don't know about.
To be fair, it depends on what you're looking for and where you're looking. There are numerous excellent resources for learning on YouTube, particularly when it comes to topics beyond cryptocurrency. That being said, some channels do try to add unnecessary filters because they want to ensure their videos can be monetized. It's unfortunate that YouTube set the rules that way, afaik.
