How i know that they see btc and eth as commodities ??
Ether is not a commodity, its PoS is enough to prove that not to talk of other reasons.
Becouse they trade btc and eth side by side with OIL contracts, and gold contracts and it's on commodities Market not sp500 and not Forex either.
When the bull run starts, you will know how altcoins follow bitcoin while bitcoin following halving if it happens ones again. That would be when you will realize that wall street follow crypto season.
