Ethfinex and Bitfinex are integrated platforms and you will be able to access either of the platforms using existing log in information. This means that your Bitfinex user information will allow you to log in to Ethfinex without requiring you to set up a new account.
To do so:
1. Access Ethfinex and log in as you normally would. When doing so you will be met with the following pop up:
2. Press Connect my Bitfinex to Ethfinex.
3. You will receive an email asking you to confirm. Confirm the connection by pressing Connect my Bitfinex to Ethfinex.
4. Log in to your Bitfinex account.
Upon successful log in to your Bitfinex account, your Ethfinex & Bitfinex accounts will now be connected. This means that your Bitfinex Ethereum/ERC20 balances will be visible on Ethfinex and vice versa. Please keep in mind that trading on Bitfinex will not earn you Nectar tokens.
Note: If you choose to deactivate one of the linked accounts, it would deactivate both your Bitfinex and Ethfinex account.
