Hashcats is a fun concept, similar to an idea I've been wanting to put out there for a while.
Problem is that it's inherently an automated ponzi, in the classic sense: new mints pay out older minters.
Mint price increases with each epoch, and floor must necessarily keep up or else you end up in a death spiral: mint price higher than floor -> people stop minting -> older cats stop getting paid -> they dump -> floor goes lower -> gap widens -> and so on
I like the idea and I think one or two small tweaks could produce a genuinely (long term) engaging ecosystem.
Might have been the push I needed to dust off my old ideabook
