i and many others are doing healthy trades at $500+ by simply ignoring those crappy exchange valued and their price rigging. we trade privately, and we have seen volume rises and alot of adoption personally, and also in the news
What do you mean you are doing $500+ trades? You pay $500 for a bitcoin while you can buy it for $360? Or you know idiots that are paying $500 for something that worths 360? What part of it is healthy?
The current exchanges are good for small to moderate amounts of money.
After the Gox crimes, some people will gladly pay a premium price to avoid sending money to possibly dangerous exchanges.
