Most of the users have been constantly moaning that hitbtc exchange might be a
Scam or they have lost their money while holding or trading them on hitbtc. Hence I have never used the exchange and will never try to use them for sure. Some users on this forum came with a similar complaint and have not got past through many times. I am not saying this to scare you, but it's the truth with this particular exchange. Hence if you had got access through your wallet successfully, transfer all your nano to a safer wallet and stop visiting the exchange. To be sure, there are lot more good exchanges to exchange or trade your nano.
Some of the possible alternatives I suggest which could solve your currency operation error :
1. Since you are dealing with Nano, I have checked the status of the currency in
this page. This exchange has a webpage for tracking the system health of a particular currency and going by Nano we can see that you
cannot Transfer or Withdraw your currency. You can just trade the currency going by the current maintenance period. Just wait for the maintenance to get over and take off the currency completely from the exchange.
2. A rare case : Someone might have gained access through your account and changed your password. If your mail has been compromised, hacker might get access to your wallet. To prevent this, the so called secured system of hitbtc locks your account temporarily until you initiate the password recovery request. You can receive the notification for password change in your account. If you hadn't requested for one, try contacting the hitbtc team.
Hope these suggestions help you.
