Canceled withdraws most often occur due to the user not confirming the withdrawal through a link in the e-mail dispatched to their official Bitfinex e-mail address. Users have 12 hours to confirm their withdrawal requests before the withdrawal is automatically canceled.
There are other instances that lead to a canceled withdrawal, as well if the “Send to” address is not properly entered. Always be sure to check and re-check that you are entering the correct and complete address. If possible, copy and paste it to avoid typographical errors.
We encourage all users to review our Greenline Conditions which significantly increase personal security, reduce the required number of confirmations for cryptocurrency deposits, and prioritize withdrawals through automatic processing.
