Thanks guys, for all your advice. I have just made the changes to the license CC-Attribution. As a token of appreciation to all you guys, I have made available the wallet graphics which I just completed as well.
OK, I re-license all of my modifications on the same license (if necessary).
Effective immediately.
I will also modify the wallet image so that it has bigger "B", just give me some time.
EDIT: Not necessary, actually.
