I've noticed the difficulty going up and not coming down, unlike the price. By the time my transfer to BTER went thru the price had dropped significantly.
Yes, same here.
You know, they might have sold off the contents of some exchange-owned wallet and delayed user's deposits in the mean time. When the user's deposit is finally credited, they could have bought back these coins at a lower price, essentially scalping the user of his profits. Just some thoughts... Not accusing them of anything, as there is no proof. Also such a scheme would be VERY risky for the exchange, as no one can predict the price for a couple of days in advance.
