....there are lots of share and ForEX trading sites who have been doing what Gox is failing to do for many years now, and with far better security and far lower fees. All we need is one to get on board and if they do a competent job they will win most market share in a very short time.
Peer2peer trading will always be conceptually better if anyone could get that to work.
That's a different matter. There are two practical problems - one is volume of trade: low fees come from having a big turnover - the second is the banks who are trying as hard as possible to block btc by not dealing with the exchange companies. There is no UK or US bank so far as I can see that deals with them.
That's why SEPA is so important for UK bitcoin because the UK banks can't stop a SEPA payment and have to convert EUR to GBP. Even then some of the scumbags like Nat West put an additional fee on top of any exchange commission when euros are sent to your account. (For every foreign transaction not just bitcoin related)
In short I don't think expertise is the sole problem.
....Also all the high fees are not within the trading section (apart from the loony tunes maker/taker crap) but the transitions and intermediaries.
Yay 10:50 UTC marked as "processed" so the Poles have got it, now how fast is SEPA itself?
