I do not really rely on youtube because not all information provided are true and others are just making advantage to scam other people through their fraud activities.

However, youtube or even google has take a huge part for us to learn more and develop.  As what has OP intend to understand that the best way to learn to watch videos and tutorials other related media.

I am suggesting to be not contented with one media to watch. It would be better also to watch other videos related to the queries in that way it would be easy to understand how things will work based on the content and how the authors of the content explain in the video.

As the say that two heads is better than one so I guess watching 2 videos or more satisfy your cravings to learn a certain aspect or technicalities of cryptocurrency.
