From MtGox's website:
I've been saying for a while that MtGox was propping up the price, now they arent even trying to hide it anymore. If the price is going to fall, let it fall...free market, bitches.
This market ISN'T free. It is supposed to be but has strong bottlenecks in the exchanges. The gox platform troubles are the very chains that prevent this market from being free. They have to fix their system and apparently are doing it right now. I personally think they should have put a cap on how much lag was allowable. 10-15 minutes max and then pause the market for a couple minutes to allow their platform to catch up. If they need to halt it to deal with those chains that is fine by me.
Calling their hardware upgrade a market cool down to deal with the dip was unwise. 12 hours is too long for something like that. The only halting should be in the immediate moment if the lag is going insane, hour+, like yesterday.
