When you put your ticket up for sale, your ad becomes visible in the secondary ticket market. This way other interested ticket buyers can buy their safe ticket from you.
You can see the status of your sale by clicking the white button underneath the green ticket image in your wallet. For example a white button with your ticket '1x Third Release'. The page that opens shows that your ticket is FOR SALE. If your ticket is sold, you will get a notification per SMS and the status will be changed to resold.
Promoting your sale
Next to the status, you can also see a green 'share' button. By copying this link you can promote your ticket on social media or with friends. This way you can give the sale of your ticket an extra push.
Cancelling the sale
If you decide to use the ticket yourself in the end, you can cancel the sale here. Note that this is not possible the moment the ticket is in someone else's basket.
