Some of the platforms right now is having a KYC verification before you can use their platform and it becomes now centralized because they want to monitor who is their customer has a large amount of wallet stored and transferring funds they don't want to be included in any legal actions that's why they need to monitor bitcoin is just only the method of payment. Still, this js the bitcoin which is decentralized.
But we still have free platforms that we don't have to do KYC verification, so we don't have to send anything to them. We don't have to afraid of the verifications because we can skip that process if we found the platforms. We don't have to use a large amount of one coin, so we don't have to make them curious. Besides that, we can prevent the big loss if we use that funds to trade.
