I've not at any point contested the differences between DEX and CEXs with you and you should really work on your reading comprehension so you can realize that.
??? Genuinely at a loss. You're conflating CEXs and DEXs to make a point about how "crypto does not prevent fraud". I said sure, if you want to include CEXs in "crypto" then "crypto" does not prevent fraud, but self-custody solutions like DEXs still do.
Because CEX's are undoubtedly part of crypto and nobody could say otherwise without being completely disingenuous. Which is exactly what our debate has been over.
