Is there any youtube channel which regularly uploads bitcoin related contents/news?
There are tons of Youtube channels available out there that tackle topics about
BTC. You just have to use the search function in Youtube and search for the topics that you wanted to learn regarding BTC. Just be careful in searching for those channels because most of them are just bunch of people talking about bitcoin with little to none useful information and they just advertise different links (referral, gambling sites, etc.) at the end of their videos.
