With no central bank and only able to look to each other, we come a network/community looking out for each other by the very nature of "this is the only way this can work, either we are all in, or we aren't"
Proof is Gox situation, where this crazy untraceable anonymous money can be found out if everyone pools their efforts to ensure one person doesn't fuck it up.
God I wish I had money to invest, back in Gox too, I swear he will come through with some of the newest/toughest security. TradeHill will no doubt have a foot in the history of exchanges, but things will be compared to with Gox.
Or not, who knows.
