The huge difference is that a stock is a stake of actual ownership in the company. You can attend and vote in shareholder meetings so with enough stocks you can actually influence what the company does. And unlike crypto there is a natural non-zero price floor, which is the value of all of the tangible assets of the company which could be sold off if the company shut down (less any liabilities).

That's not to say that the majority of investors, especially algorithmic traders, treat it any different than crypto/gambling.

No that Bob is quite a bit older and hasn't got into sports broadcasting, at least not the last time I checked... ;)
