I didn't say it was only for stocks or other investment vehicles but I've invested enough money over the past 50+ years to have a decent feel for what makes sense and I'm actually quite educated there.
Trading commodities, T-Bills, T-Bonds, Grains, Oil etc, as this is a kin to is not investing, it is gambling. I've done all that and was fine with it and in fact had real time feeds coming in back in the day when I did it. You do not own an underlying asset. You are buying something and hoping it goes up, down or sideways depending on how you purchase it.
Buying into actual companies is investing (there is a gamble there as well but you have an asset under you), trading is not investing and this is nothing more than that.
Yeah, I'm educated there on many levels.
