I just saw this now but Oh my! There is big scope for this; if the potential is utilized to its max extent. There are very few good crypto channels on youtube as many have failed so I would suggest research first and then dive in. Crypto channels have been known for having horrible retention rate(for how long does an average user watch your video).

Considering the channel being focused on bitcointalk particularly, I think a banger episode will be to start off from Satoshi and the history of bitcointalk. Not many know how BTT actually came into place, and how bitcoin actually found its community. Sure the community awards is cool and all, but I guess if you're to start a legitimate channel, I really do think starting from Satoshi would only feel right.

Moving forward a lot of content could be split into:

How-to-bitcointalk: Content/videos going around how to use bitcointalk

How-not-to-scandal: This would be a fun idea where you could go over past scams of different extremes uncovered on bitcointalk

Community-shoutouts: vidoes that go around thanking members who have been the core reason for bitcointalk being a fun place for all these years.

studying-sundays: educational content on how to crypto.

Story-saturdays: Cover the stories that happened exclusively on bitcointalk, like: pizza for 10k Bitcoins, Hal Finey, the story of Bruno etc etc

Future fridays: Cover theories on how crypto is to evolve in the future and shut down dumb theories. idk I could come up with more ideas, but how are these for now?

Obviously there could be giveaways, merch, community games etc and even livestreams. I know achow101 does livestreams on twitch sometimes soo you know you know big things for btt. #to-the-moon
