Well I would not trust YT for such stuffs. There's always that possibility that they were paid to do such thing. Any small youtubers could do this just for the sake of earning money of course. With crypto, I watch videos in Youtube just for the sake of learning the technical sides of trading back then, but I do not buy everyone's advice to buy this x and y coin for xxx% APY.

Sure podcasts could be a good thing for trading advice, but that does not mean that you are entirely going to risk it because someone told you so. Imagine being asked why you bought this coin and you answered that "because I was told by a certain youtuber to buy one". It's better to DYOR like always.
Best of luck to your investments by the way!
