As a long bull I am feeling very bearish. These Mt Gox issues are bad in my mind. People are happy Gox is losing market share but for me it's more like the lynchpin of the bitcoin ecosystem is failing due to political forces. If the bitcoin processors are dependent on gox then we are close to the point where retailers give up.
Yes. A healthy MtGox is good for Bitcoin. Bitpay and others need a proper fx market with depth to maintain their business. The other exchanges are too illiquid. I think that people who want mtgox to fail are mostly those hoping to buy BTC at 2012 values because they missed the ramp up this year.
I think that most of the people who want Mt. Gox to die, know that things have to be purged in order to improve. Right now we pretty much only have a one headed Hydra, but if Mt. Gox were to go down in flames, or lose its market share, it would only diversify the commerce, instead of depending on a single weakest link. As we are, we depend largely on a single headed Hyrdra, that isn't always constant, but if we had others to diversify in, we'd have much less collective risk.
I think that the people who want Mt. Gox out of the big picture are the same people who want a decentralized currency.
