There are no known issues with sending ETH and ERC-20 tokens to external addresses, so long as the wallet or exchange you are sending your tokens to supports the token you’re transferring. If you’re not sure if the ERC-20 token* is supported by your wallet, please check with our customer support first.
You may start with sending the minimum amount possible. Only if the transaction is successful, proceed with sending the whole amount. While it may be more costly, it is definitely much safer - do remember, that once a transaction is posted to the blockchain, we will not be able to stop or reverse it.
*ERC-20 tokens include: KOZ
