This could end very badly for Bitstamp. If the buying slows down enough from most of the traders on Bitstamp exhausting their supply of dollars, Mr. 30k might keep reducing his ask price until he has sold through most of the order book. That would leave everyone else on Bitstamp with lots of bitcoin and only enough dollars to support a far lower price (probably under $100). At that point, people would rush to move their bitcoins to a different exchange to sell them. The only things that would prevent this from happening are a lot of dollars that aren't currently being used for any orders or the 20k wall being bought very quickly or pulled.

What hardware are you trying to use for mining? Also, it can take a minute for cgminer to actually do anything.

You need to use cgminer 3.7.2 or lower.

Go to Help > Debug window. What are the values for "Number of connections" and "Current number of blocks"?

I just started using RTBTC and I've noticed a problem when trading with Bitstamp. Orders disappear from the order book as soon as they've been at least partially filled. Orders that have not been completely filled should obviously remain in the order book, but they don't. This doesn't appear to be an issue with Bitstamp because the live order book on their site continues to show the orders, and they only disappear once they've been completely filled or cancelled. I'm using v0.2.9.

I've also noticed that the account balances often don't update for a while or at all, but that could be a Bitstamp issue. I'm aware that their API isn't the best.
