we're in the Wild West days of open-source currency. I expect people will get burned by scams, imitators, ponzi schemes and price bubbles..
I tend not to worry about things that are out of my control; I don't think there's a whole lot that can be done about scammers, imitators, and ponzi schemes besides warning people to be careful with their money (whether dollars, euros or bitcoins).
there are many people who hold an opinion on the matter but they aren't outspoken about it. when each of these ponzi fund house of cards falls, some people will be hurt badly, others (those who have made most or all of their money back already) will barely be nicked and most will feel no impact at all as they were smart enough to keep a healthy distance. you don't hear from them. you probably won't, even if they were asked for their opinion.
this is definitely a circus but it is nowhere near to being significant in bitcoin's progression. just as few today remember or care much about last year's mtgox hack or the mybitcoin fiasco, this too shall pass.
