Why does anyone follow YouTube advise

Am I being overly cautious and missing out, thinking that 99% of YT video are people scamming and just promoting their bags to offload at a higher price?

Is there any channels worth following for general updates and knowledge, that are not just promoting certain coins/exchanges.

Any recommendations for other sources to use for keeping up to date. I follow a few project that I’m interested in just want to broaden my knowledge. Not looking for individual coins etc more general overview.

Of course this sub is great, just looking for additional sources!
