Thanks for sharing the video. I’ve watched a lot of his videos. My conclusion is that he uses a lot of hype. The “crack” part of his name in YouTube attracts a lot of attention. But ultimately his material is very naive, short-sighted, basic, and not very useful for those who are actually deeply involved and vested in the mining. The entertainment value of his videos is greater than the learning value.
I’m not faulting you - the guy is entertaining. But be careful that you don’t take much of the content as good advice.
