A deposit address is a transactional address on a cryptocurrency network used to link deposits to individual user wallets on the Bitfinex account.
Any address created by you will remain associated with your Bitfinex account, and deposits will be credited to it. However, if you have changed your address for a certain currency, you should start using your newly generated address for future deposits.
Note: We will notify you in the rare cases where we will need to update addresses, and reusing old addresses may result in delays and possible lost funds.
If you have any questions regarding your addresses, feel free to contact Bitfinex Support for further assistance.
