This are for those who mostly love using swap, that is Decentralized exchange rather than central exchange, of course many people wouldn't want to go through centralized exchange due to privacy issues and they wouldn't want to pass through their verification process so they could decide to use the Decentralized exchange.
Automatic swap services cannot be called decentralized exchanges, they still have a lot of elements of centralized services. And many of them, even those that claim to be NO-KYC, can still block customer withdrawals and ask for KYC, so with them you could still end up passing KYC verification.
That is why people are advised to research very well before picking an instant exchange, because a lot of them are scam platforms or data farms, or both.
