There is one advantage that centralised exchanges have, scammers who have stolen some Bitcoin don't come close to such platforms because they can be caught all because of KYC information, stolen bitcoin or bad bitcoins don't get sold on centralised exchange, they risk seizing or arrests, always use reputable exchanges.
Some mixers, decentralized finance (DeFi) platforms, and privacy-enhancing services manage Binance OKX Kucoin accounts as part of their liquidity providers. KYC policies do not prevent money laundering, anyone can buy high-quality cryptocurrencies at a low price or even spend $1000 to buy cryptocurrencies from countries with lax KYC policies.
