KuCoin is one of the largest cryptocurrency exchanges in the world. KuCoin supports trading for CFX on Conflux eSpace.
Note to Binance users and bCFX holders: Conflux on Binance is listed as wrapped ERC-20 token, it is not native CFX. Conflux eSpace and Binance SmartChain use EVM-compatible addresses, but those addresses live in different chains.
For clarity's purpose:
KuCoin lists eSpace CFX, the native currency of Conflux eSpace.
Binance lists wrapped CFX (or bCFX), an ERC-20 token deployed on Binance SmartChain.
You cannot transfer CFX from KuCoin to a Binance wallet, nor to a wallet that is connected to the Binance SmartChain network.

You cannot transfer natively bCFX from a Binance SmartChain wallet to an Conflux eSpace wallet, nor to a KuCoin wallet.
