I don't understand why an exchange like cavirtex needs to charge such a high fee per trade, and why that fee needs to be charged as a % of the transaction? Even Gox charges a %. I am aware there are costs in running an exchange but these exchanges should be mostly automated by machines.... So why does it cost so much more to facilitate a $1000 trade vs a $1 trade? It's just a computer processing a different number, there is no need for it to cost so much extra.

It seems to me like there should be room here for people to build an exchange using waaay lower fees, why has this not happened yet? One of the points we always use to sell bitcoin is the "no transaction fees" but buying and selling your coins comes at such a high fee so it really doesn't matter - unless you stay within the btc economy of course. But for instance trying to send money to a relative across seas would still come at an exceptional fee.

I really think this problem needs to be solved in order to help bring btc to the masses but I just don't understand why this problem hasn't already been solved on the free market.
