I have previously shared with you how to Earn NBX Coin for free Earn From A Browser - Netbox.
So, while I was searching today. I have found an exchange that have the NBX/ETH pair. There are others of course. But, I am going to discuss Crex24.
I will just skip the part where you need to create an account with Crex24..etc. So, all you have to do is to go to Instruments on the right hand side. Select BTC or Eth and then search for NBX.
Once you are done. Scroll down to where it says Sell NBX.
Click on Best bid and then, enter the amount of NBX you have and click sell.
Assuming that you are not familiar with how to fund your Crex24 account. Just follow the below steps.
Click on Account Tab and then click on the icon for deposit next to the currency that you have.
You will be presented with your NBX Coin address where you need to send the funds from the NBX browser.
After finishing the exchange, you will come back to this screen to withdraw your funds in ETH/BTC to your wallet.
