- Sell walls are fake at Mtgox.
i just witnessed the 9.5 sellwall of 5000 vanish to ~300 BTC, when the price was at 9.45. then a couple minutes later, it is here again. i expect it to vanish totally one the price gets in its range.
but in fact think it is possible that the price falls down quickly, the bids are very, very shallow. just a selloff of 1k could demolish the price, down to 8.5. so it might be a very risky thing to hold bitcoins at the moment..
