Be Careful With Exchanges
Most wallets are non-custodial, meaning you control your own private keys through the recovery seed. Exchanges are different. When you send your KMD to an exchange, you don’t control the funds anymore; the exchange does. Don’t store large amounts of KMD on exchanges longer than necessary. It’s best practice to withdraw your coins as soon as you've finished trading. Or, better still, try AtomicDEX wallet, Komodo's non-custodial decentralized exchange.
