I transferred eth to metamask then converted it to dai. Now I need to send the dai to kucoin. Dai is listed on kucoin, but I'm wondering if I'm allowed to send dai or I can only send and receive eth?
Metamask is an ERC-20 supported wallet. You can store any ERC-20 supported token or coin here. ETH will be deducted as fee for token or coin transactions. You can deposit your DAI stablecoin in KuCoin or any other exchange. Just keep some ETH in your wallet for fee.
