it will probably be mostly remembered as being sort of a spark that ignited a lot more I'll bet.
This could be a reality if the big players in fiat transactions get involved. (Think paypal issuing an eBay coin or Visa issuing a
real Visa coin). Expect massive advertising budgets, FUD, misinformation and the smear campaign against bitcoin and its users.
The majority of the public are not yet 'on board', there will be a war, the big players are just biding their time to strike.
Makes a lot more sense to simply appropriate Bitcoin and it's existing credibility. 90%+ of the current users, and a higher percentage every day, consider Bitcoin credible because someone else does without much concept about why.
Anyway, if/when blacklists come to town, controlling the blacklist entity is effectively controlling Bitcoin. For people who know how money works that is fairly obvious. I'm sure that is why we see the Mellon family (
