...There is nothing stopping the CME from including scam cryptocoins and tokens in their market. Like what they did in the past, they will combine different scam altcoins with bitcoin in tranches, and have them rated as class A investments.

I think this is pure conjecture. I couldn´t find any claim that the CME group actually has any plans to offer any products related to altcoins at all.
Why would they even do that? The liquidity of the majority of altcoins (with the exception of maybe ETH) is way too low to be suitable
for any sort of derivatives. Additionally, it is very doubtful whether it would be even legal for them to offer any products related to this due
to the regulatory uncertainty surrounding most of these cryptocurrencies.
