Has anything fundamentally changed with Bitcoin in the past 72 hours? The last time I checked, MTGox was signing up 20,000+ people a day, and our biggest problem was that people can't get coins fast enough.
72 hours? No.
24 hours: it may be that any panic sell-off is mitigated or even negated due to Mt Gox being ready to halt new trades on a lag spike as they've successfully done several times now.
The lower threshold and shorter periods of this allow only a limited amount of reaction to the lag and imminent panic sell-off.
This is the single biggest reason I am bullish for the next few days and am holding coins and no cash.
