MtGox has reduced their commissions (at least temporarily) to 0.3%. Are you going to match that? How hungry are you? You must be aware that you have to bring something extra to the table to compensate for your relatively tiny volume, right?
We've got a few things lined up. I don't think we need a price war but I'm sure it will happen eventually.
There are a lot of ways to compete outside of price. There isn't a war between TradeHill and Mt Gox and I consider the competition pretty friendly. Besides people should be diversifying. Don't put all your money on Mt Gox or TradeHill, spread it around.
