I agreed with the list but don't you think it time to update the list because there are other gambling site's that are into bitcoin gambling such as bustadice and stake this are other gambling site's that are offering bitcoin as a deposits and placing of bet and game's. We need a new poll since those on the list are gradually moving to extinction.
Any survey and its results will become obsolete after some time. It is best to create a topic and reserve messages for posting new polls and lists.
You can try to create a similar topic yourself.
