im pretty sure almost everyone on the forum believes in bitcoin.if they didnt, what would they be doing on this forum lol.
as for myself, i think bitcoin has great potential, which is why im holding on to it. until it skyrockets.
People who don't think Bitcoin will be a future currency or when they simply don't like it enough, they just stay here for the signature campaigns to earn some bucks. Just look at the newbies who are joining as their first posts are 'Where can I join a signature campaign?' & 'How to earn money quick?' etc.
