What podcast / youtuber do you suggest?

I first started watching / listening to CryptoCasey but got annoyed as 80% of her videos seem to only be about advertising companies that sponsor her.. and 5% conspiracy theory that the entire gov't is trying to destroy people. There are a couple others I've tried finding but I seem to be fed people who are dramatic and cause trouble (bitboy and people that talk $hit about him).

I am almost completely just into BTC - not into random start ups. I'm hoping to continue investing long term for 10+ years before I retire.
