I share your skepticism. But I'm trying (forcing) myself to keep an open mind so I don't want to completely dismiss the strategy. I listened on a podcast where a crypto algo trader said he's been using it successfully in his fund: https://bettersystemtrader.com/algorithmic-crypto-trading/

I've also heard on that podcast a good explanation for why traders bother selling courses even if they're good at their jobs. Trading is volatile, so you want to acquire alternative income streams. I think that's a point that any entrepreneur would find reasonable.
