If watching a 1hr+ youtube video can help me reduce the risk and increase the chance of earning profits, I would watch it. I definitely did watch some of them, most of my knowledge and information about this cryptocurrency world was gained by watching videos and reading articles. The important thing is that you have to choose what to watch!
If you recommend something and your rank is good enough to consider then I too will not be having any hesitation on studying/watching something that got the potential to transform something in rest of my life. But, if you start listening to random people, I am afraid your life cannot be enough to cover them all. Filtering the noises out is key here. Because, in most cases people who are recommending something are paid shills and/or doing them for affiliate reasons.It would be just better if you do just highlight or giving out the keywords on this thread but in talks of risk management then it do mostly cover up common sense thing.
When people are posting video links for the reason driving out big traffic from this forum, how can we expect them to provide keynotes out of those videos.. 
There is a continuous demand on regulating clickbait links until then we need to get practiced to live around them.
