So nobody treated Buttercoin seriously because of the name
But people sent millions $ and BTC to MagicalTux and his Magic: The Gathering Online .
When I first heard of Mt Gox I didn't know how it got its name, it was merely an unusual name to me. It took months before I heard it stood for Magic The Gathering Online Exchange. Conversely, I immediately thought Buttercoin sounded like a stupid name as soon as I heard it.
Mt Gox had a chance to gain business partly because it was only after people got used to trading on it that they realized Mt Gox was an acronym for a stupid name.
