I'm just curious what the effect is of 24/7 trading on all these wide swings besides other factors such as Mt. Gox lag etc? People in one part of the world go to bed and others are awakening to see the price plummeted or vice versa. Or is this a non issue?
That's the same in real life.
When American and European market is closed for buying and selling EUR and USD, the japanese market opens.
The only difference is that the markets are closed during weekends and holidays.
