Adhering to FOREX trading hours (23 hours / day, 6 days a week) or CME GROUP hours (15 minute downtime per day, weekends off) means more planned stability. And, as I said, a window for handling maintenance.
Absolutely not. We don't play by old economy rules.
Make sense. Let's ignore reality and live ina a fantasy world.
Yes, you DO play by old economic rules. You also play by standard IT rules which LOVE planned downtime. 24/7 is extremely hard to maintain for anything not a joke website (mt gox still is there - joke website - wait until you see real volume, options etc.).
Plus somehow Bitcoins dont live in a fancy fantasy world - exchagne against funds requires funds available, and as the OP pointed out, lots of the non-bitcoiin infrastructure shuts down on weekends.
The rules of the old trade markets are the fantasy world. The economy does not sleep at weekend.
