I lost the 0.25 BTC you recently gave me. When I try to "play for bitcoins" I'm shown my deposit address, and the message:
"To get started, send some bitcoins to your personal deposit address. Your bitcoins will instantly be available to start playing!"
I send some bitcoins to my address, but the message stayed there. Is it meant to update automatically, or do I need to refresh the page? It would be nice if you could push an update when you receive my deposit, but I don't know if that's possible. If not, maybe you should mention that a page refresh is required, or have a button or link for "refresh my balance" or similar.
(Refreshing the page shows the deposit went through OK, so it is just that you're not updating the page when I deposit)
Dealing with usability in my day-job I would suggest adding the button anyway.... it eliminates user questions (dooglus is not your average user, and he had questions).
Even if you rely on some sort of push and just disable the button for 5 seconds it makes the user 'feel better'.
