There is a vacuum to be filled, it will be filled, and it will be a lot better than MtGox. Fast forward 12 months and we will have completely different (and competing) players. Until then, enjoy the bumpy ride

Of course new companies will attempt to step up, but the biggest problem is that everyone who wants to trade will head straight for the most popular one, because the most volume is there to trade with, and voila, today happening again is inevitable.
Without major action, this cycle will continue forever... And as long as it's happening, Bitcoin cannot be a Currency... Too volatile.
How about an MPEX-style solution? A well-capitalized company opens a premiere exchange, and rents a limited number of "seats" at the exchange, say 100ish seats, for some market-determined rate.
Hmm, I'm having trouble imagining MPEx with so much organization and money behind it. Could you elaborate? Where is the capitol coming from? How will it be organized? Where will the real-time trading come in? Etc...
Decentralised exchanges already work, but they cannot play in the same league for trading speed.
Could you point us to one that works?
There's got to be a way to add some real-time trading to the mix... Even if it's just some sort of a session that pops into existence for a region...
You cannot decentralise bank transfers without friction. There is P2P trust and other considerations.
I hear you, but if we just solve some of the problems we may be able to hybrid the system between other, existing exchanges and have no central point of failure... Worth a mental excercise, at least.
My prediction:
MtGox will improve their performance and for the time being things will continue "as usual". I don't think this is going to change any time soon.
Not without some real answers.
...And again, until they appear, bitcoin will never be a currency that the masses can accept.
