In keeping with my attempt to wean myself off of Google services, I haven't been watching YT videos nearly as much as I used to and probably won't check any of these out (but I haven't decided yet). Nevertheless I appreciate the links, OP.
From what I've seen over the years, the quality of content when it comes to videos having anything crypto-related as their theme has dropped to the bottom of the cesspool that is Youtube; right now it seems like there's a lot of misinformation or simply lazy video creators making at best mediocre videos for the sake of making money through ad revenue and/or sponsorships--kind of like shitposting here on bitcointalk, you know?
On a related note, whatever became of this forum's own YT channel? It never reached the popularity many of us were probably expecting, but I always liked it when a new video came out.
