From my own perspective, I think Bitcoin fans are anyone who has an open mind and a practical attitude and I think I could say the opposite to the Bitcoin haters. Maybe they don't actually hate bitcoin, it's just that they have a different understanding about it. Some would say that these aren't all true and some would say that Bitcoins in some other countries doesn't have supporting government bodies. Well it's fine to have such variety of opinions but still, there are more people who believes in Bitcoin than hate it. That belief can still make the Bitcoin world grow larger and larger.
