It brought in those who lived a lifestyle of satire and burlesque. People who spend idiotic amounts of time browsing the internet all day looking for the funnies .. likely to be associated with a nerd consumer culture in which memes were already ubiquitous. These are the people who spend money wastefully on browser based games linked with social media, browse various internet forums for no real reason other than lacking a hobby, or job (generally because they're locked up in an apartment for 10-14 hours a day and going stir crazy - but can't afford to do much else than internet based hobbies). It brought in many Americans who saw it as the punt. These same people only ever focus on the punt, because they're generally onto the next punt before the first one lands. These punts are free so the attention span is microscopic.

It brought in people that wanted to see bitcoin as a joke, and a satire of it was a digging dog that speaks in its own dialect. It fit into the subconscious of people that are completely miserable, and made a joke from the folly of their poverty -- and even then told them they'll be rich beyond all else because of their folly. It fit well because it was an accurate description of what people think this is all about - a cult of people digging for electronic gold saying things that make mostly no sense. It was a comfortable description, and I haven't really seen much to say that it's not an accurate one save for people telling me it's gonna be worth something some day.

Understand that these are my opinions, but I don't think it's a flight of fancy to say that this is largely true. Personally, I think that there's more here .. but take what I wrote for what it's worth.
