Corruption is probably a bad description. It is more like what happened to Tulips during Tulip Mania, or Beanie Babies during that bubble. Beanie Babies are not "corrupted". They are "associated" with a bubble. Crypto as a whole is becoming increasingly associated with zero sum scams like Ponzi/MLMs. And it is partially due to the fee extraction entities that are making a profit of off the "investor's" cash.
I mean Mt Gox was almost a decade ago. Bad people try to do bad things with other peoples money.
That's the value in bitcoin though. You dont need to use these exchanges. If you're smart, you dont trust large institutions of any kind with your money.
That mitigates these risks for people who are able to have an in-depth understanding of Bitcoin, which is in itself extremely complex and requires tons of prior knowledge. Everyone else has to trust someone with their crypto needs and is left to be fleeced with no recourse at all. As of now, that merely replaces the group that profits disproportionately with a crypto bros and the like.
