THANKS @grow-pro!
I just traded my balls for steem (LoL).. These guys are on top of it, so don't be concerned with payment, they will send you the funds as soon as you transfer the balls.. you can look in my wallet to confirm it if you don't believe me.. This is so much better than sending them to an exchange where you will have to pay fees! So don't hesitate if you wanna sell your balls, this is the place to do it!
