There is, but I haven't configured it.

I don't use NameCoin personally.

I'm happy to announce that Bitcoinica users don't have to wait in line for Mt. Gox code withdrawals any more.

The new version of the mtgox Ruby gem (0.7.2) now supports Mt. Gox's key-secret API authentication, which means that any account protected by Yubikey can still utilize the "very secure" API authentication to withdraw. As a result, now Bitcoinica users can withdraw using a *verified* account with a much larger withdrawal limits.

However, the "manual approval" feature is still there. Large withdrawals are subject to manual approval (usually within a few hours). Most users won't ever hit the threshold.

Thank you for your support!

I have credited the 5 BTC to you.

Thanks!

At the point of $4.50, there were a lot of forced liquidations, stop orders and market buy orders, and there's almost no depth beyond the price until $4.90. So the algorithm decided that the price should be set at $4.90 to minimize the risk for Bitcoinica based on the actual situations.

Then there are sell orders and price decreased, so the algorithm relaxed and lowered the spread. And the previous high were proven wrong.

It's important to know that currently we always have a chain of forced liquidations, because forced liquidations will push the price to trigger more forced liquidations. We will just make sure that they are fully hedged in the market and the prices are reasonable.

I understand what the original 5 BTC means to you. But well, why can't there be a tie? You deserve it as much as Goat did, and old_engineer wasn't wrong at all to give out only 5 BTC for the contest.

Just post your username and I will send 5 BTC to you immediately. If you don't want to trade on Bitcoinica or don't like it, just withdraw it right away. :-)

the_joint,

Welcome to Bitcoinica! I will send you the f**king 5 BTC to your account for you to start trading. You made a pretty great guess!

(This is off-topic forum, so I posted this off-topic stuff.)

Seriously, if I work at Mt. Gox, I wouldn't be able to finish margin trading in a year. Mt. Gox has a very professional trading engine and I don't know how to add margin trading facility effectively.

That's why Bitcoinica is not an exchange and will never be. I initially had the idea of Bitcoinica on September 3, shared with a few friends, and then launched on September 9.

As requested by some of you, the hedging data is now available on Bitcoinica home page.

Now you can know the percentage of Bitcoinica trades that were hedged at Mt. Gox in the last 24 hours. Please be reminded that this may not be 100% accurate as some orders can remain "open" when the prices are changing too quickly.

We have a very useful feature coming soon this week. Stay tuned!

If we liquidated the customer's assets at $4.50 but we charged the customer $4.90 for it, I would say $0.35-$0.39 should be the unexpected profit.

On the other hand, if the customer's assets shouldn't be liquidated at the price of $4.50 instead of $4.90, the better solution is to reverse it.

Mt. Gox code is good if you have a Mt. Gox account.

Wire Transfer is also cool. Super fast transfer (most customers receive funds on the next working day). The fee is $30 SGD or about $23 USD flat.

Actually I did reverse/refund those obviously inaccurate forced liquidations. But it just happens that some were missing (excuse me hundreds of orders come at once).

Can you send an email to support@bitcoinica.com about this? We'd like to compensate you on this.

While it's true that our algorithm sets the price by balancing and predicting the benefit and the risk, after all the trading, there's no point of predicting, and we can clearly see that the prediction was wrong. So we are perfectly okay to refund you the "unexpected profit" we made from you.

I hope this explanation makes sense.

I will check the code and see if everything is right. Perhaps I broke something since the last minor update. I apologize in advance!

A lot, seriously.

We are not trading against our customers. There's seriously no depth above $4 at that time compared to the massive forced liquidations. Bitcoinica, as a market maker, has to offer guaranteed liquidity on the price displayed. There's simply no better price to offer according to our algorithm.

We have recovered all the inaccurate forced liquidations as a result of this spike.

Sorry for the problem. Just now someone used API to spam us with tiny orders, and unfortunately our matching algorithm spent a long time processing them.

I have already optimized the code to process orders on user-by-user basis so similar things won't happen again.

Thank you for trading at Bitcoinica!

Also, I'm not hiding anything. In Bitcoin community basically we rely on personal trust and reputation a lot. The legal backing is just an extra enforcement. You don't have to trust my company more than myself.

In Delaware, any corporation must have a registered agent. You simply can't incorporate elsewhere other than "a $99 website". Also, all the personal information is held by the registered agent instead of the state office. It's the partner's responsibility to ensure my eligibility to commit and enforce a contract, not the state's.

This is definitely remarkable, but I'm sure it's temporary too.

Bitcoin can almost never gain stability unless: 1) the price rises to above $100, or 2) it dies.

The potential instability is still there until the price is high enough to push market cap to an astronomical number.
