Dear trader, in the past you have performed one or more XMR deposits to your HitBTC balance. To do that, you have used your own deposit address, generated in your HitBTC account.
Please do not use any of these old Monero deposit addresses to send coins to HitBTC.
Instead, you have to generate a new one in your account. Select XMR in the list and press the "Create new" button in the Deposit section. From now on use this address for receiving Monero deposits.
In case of any issues with generating your new Monero address please contact us.
