I have mixed feelings. On the one hand centralized exchanges are not ideal, they deviate from the initial idea of Bitcoin, they require KYC and they can sell your data or hackers can steal it. On the other hand, they are largely responsible for the price rising from less than a penny to tens of thousands of dollars because of the great liquidity they provide.
That's another one, that some exchanges may be scams or ponzi schemes like FTX, but hopefully this will become more and more unlikely.
