Sadly ponzis with dollars are old news. This will be news and something for the anti-Bitcoiners to laugh about in the coming weeks and months. Much like the hacks and thefts they will lump the idiots who though 7% interest per week wasn't a ponzi in with every users and bitcoin the currency in general.
However in time it will fade from memory and bitcoin will still be here. At this point there is enough proof/reason that Bitcoin is viable anyone not convinced will only be convinced by the passage of time. 1 year, 3 years, 10 years when bitcoin is still around those people who ignored and laughed at it will start to doubt their first impression.
However that is long term, in the short run it makes the bitcoin community looks like a bunch of idiots. The fact that a large number of people called it a ponzi from day one will be overlooked. The stereotype is that we are a bunch of bumbling idiots who get fleeced by cons, scams, hacks, and ponzis.
True, but that list above is handy for the upcoming forum wars.
