what happened to all of those crypto exchanges offering cashback cards?

As the title suggests in the past i saw a lot of exchanges offering debit cards with cashback associated to how many of their own tokens you stake, the most famous one being crypto.com, but there are a lot of them.
Not considering binance, where it's own coin is doing actually pretty well, there are a lot of places where the token lost a lot (even more than 90%) of its ath value and in some cases it made sense like the already mentioned cryptocom it slashed their rewards in half and from that CRO, the token tanked a lot, but there are a lot of them out there where they didn't change the rewards and even there their token dropped significantly (on the top of my mind i can think oh hi crypto, that went from an ath of 1,24$ to not even being worth 1 cent).
So the question is, why did a lot of them dropped in value or disappeared if the rewards where the same and they didn't have a lot of problems to begin with? was it because of a general distrust in crypto as a whole?
