On: Bitcoin Value Loses Its Mind as Trading Lags on the Mt.Gox Exchange

[Retric]

How? Assume it's binary buy up to x bit-coin's at 835 and sell all of them at 875 does not leave a lot of room for manipulation.

[TrainedMonkey → Retric]

Because past trends do not predict future. You buy bitcoins at $835 and instead of going up to $875 they drop to $100.

Why bother with bitcoin? You can do the same with GOOG stock too.

[dnissley → tedunangst]

Stocks aren't quite so volatile.

[aparadja → dnissley]

Borrow money for more leverage. Or buy derivatives.

[PeterisP → Retric]

Even if your assumptions of 'correct' price range would be 100% correct, there's an old saying "the markets can remain irrational for longer than you can remain solvent". If you buy bitcoins at 835, and the rational longterm price is above 835, then there is still a serious risk that the market price will remain much below 835 for an arbitrary amount of time.
