I like him. He's zero bullshit, humble and therefore doesn't mind saying what's a struggle. Ducks and dives a bit selling advice but who doesn't if they're doing trading vids on YouTube.
I think it comes down to what you want to learn.
If you just want spreadsheet facts and trading methods then frankly anyone can tell you those, even your butcher. If you want to be taught how to turn that into success you need to find someone who's been on that journey and is a good teacher.
Lots of successful people can't teach because they've forgotten what it's like to be a struggling student or never were one, or don't know how to get the best out of different types of people. Teaching is a million miles from trading so finding someone who excells at both is rare.
There's many that can teach a few, but very few that can teach the many. I'd be inclined to ask, how many people have you taught, and how many are as successful as they hoped to be? Ie What's the odds of them delivering.
