Pick an exchange that lists CFX
CFX is listed on Binance (highest volume), Coinbase, Kraken, MEXC, KuCoin, Bybit, Crypto.com, and Mudrex (India). Pick one based on three factors: which exchanges are available in your country, fee structure (most charge 0.1-0.5% per trade plus a withdrawal fee), and whether you already have an account somewhere with KYC completed.
