The best way to anonymze your crypto after buying it from KYC exchange (If you have to) is exchange it with #monero on a trusted DEX (Desensitized EXchange) something like changenow.io and do couple of transaction in different period using your own node or an onion node. After that you can keep your Moner#solana or #ethereum first then exchange it with monero, after that to your target cryptocurrency. Notes: - Send it first out the KYC exchange to your own wallet then to the DEX, don't send directly to it. -
