Redeem ticket suggestion...
I accidentally redeemed my lvl2 ticket into bitcoins. I couldn't find a explanation on the "Your Stash"-area and since I'm lazy I usually go for trial and error and pressed the redeem button. It converted my ticket into bitcoins. I really think there should either be an explanation on what that button does or some sort of verification if you really want to redeem the ticket.
I use dual monitors and when I'm in game my mouse sometimes isn't focused on SC2 so I have to press outside the game into my other monitor and I usually do this very quickly and might press redeem if I'm unlucky ^^
Just a suggestion!
