If you're wondering why $ZKJ from @PolyhedraZK and maybe soon some other altcoins are en route to pulling an $OM, it's not really that much of a surprise.
Summer = Low volumes
Low volumes = Less fees for CEXes
Less fees = Higher odds of delisting
The teams decide to crime it up until they ultimately crime it all the way down - since delisting is coming in a few months anyways, and those yacht parties won't pay for themselves.
Might as well get a few dollars on the way out.
