The government is the biggest scam ever. The Fed and banking system is just the hairiest roach in the building.

Good luck! Although I hope you will still keep some bitcoin savings around, right? You never know what the future may bring.

Hmm, I don't put much stock into this astrology stuff. However, I do believe that sunspot activity and economic activity has been shown to be correlated.

Dang, I don't know if I should be happy or sad. I mean, I want bitcoin to increase in value, but I also want to get my grubby hands on as many of them as possible beforehand. So conflicted...

Bitcoinica: Salted BCrypt with 20 iterations. Enforce minimum 8 characters. It can take months to crack a simple password. (And I use this for all my future app projects. Also recommend everyone to do the same.)
I assume you mean Salted Bcrypt w/ workload=20, that is 2^20 = 1 million iterations. Slightly harder. A single round of bcrypt takes roughly 5x the clock cycles as long as SHA-256 (OpenCL optimized). Thus bcrypt(20) is on the magnitude of 5 million times harder to crack than salted SHA-256 hash. Another way to look at it. If a hacker could brute force a given password hashed SHA-256 in 1 second it would take them 57 days on bcrypt(20). There is absolutely no reason to use anything weaker than bcrypt (or similar chained iterative functions like PBKDF2 or scrypt). pass - stupid MD5(pass) - cryptographically weak SHA-256(pass) - vulnerable to rainbow tables SHA-256(pass.salt) - vulnerable to brute force bcyrpt(pass,salt,2^10) - vulnerable to weak/common password list bcyrpt(strongpass*,salt,2^10) - computationally infeasible to attack strongpass being enforced by the site as 8+ char not in dictionary not in known password list And the best part about bcrypt is that you can dynamically adapt it over time to keep up with Moore's law. Just update the hash whenever after a user successfully logs in with the updated difficulty level. With the SHA family, you're stuck.

A few updates: - Made a small improvement to the backend analysis code today
- The model issued a fresh buy signal today on a very liquid asset, so we're ramping up our purchasing in this area
251 222 IPO shares left - now is a great time to get in!
Take care, -cyto

Here's a clue. If you are using statistical methods for trading based on order book movements you can eliminate a lot of the distortions created by the 'walls' with smooth bootstrapping.
Interesting, I've never analyzed this type of stuff before. Do you have any more info on how to do this? Thanks.

Yes it is risky, but the upside is nearly unlimited.

can we go to the moon next week?
Everyone knows the moon's made of cheese... Mmm, cracking toast Gromit!

I'm having trouble logging into glbse. I have reset my password and created a new one but the site says that my username/password is still incorrect. Can someone put me in touch with someone who can help. thanks
I had a similar problem, but the solution is in the fine print. After you reset your password, then go to the GLBSE and log in. After you log in, it will take you to the error page - BUT, if you read the fine print, you will see that it says "you may have been taken here because you just reset your password". So you need to login a second time from that page with the captcha thingy. From there on out, the new password should work. Good luck!

The USD will die, by the hands of the federal reserve, we just need to count down the days. Manipulation of economies is what they do best... It has already lost its world reserve currency holding, its all downhill from here.
The day that treasury rates begin to rise is the beginning of the end. I don't know what the new reserve currency will be, but the dollar's last stand will be during the current debt crisis. Then it will go the way of the sterling IMO.

... I'm very glad to see other funds thrive. Although they may bring some competition, the bullish impact of them to the GLBSE market is sweet. I agree. The GLBSE is growing so rapidly that I'm sure it will accommodate a large diversity of funds and strategies. There are always more companies springing up, which means more opportunities for everyone.

Bitcoin looks alot healthier than this: Smells just like Japan in the late 80's...

What's wrong with GLBSE? In any case, there's a new one coming, called Hermesand there's BitcoinBorse, which is German... It certainly makes my life easier that there is only one large exchange. However, more competition means lower commissions, which helps everyone.

A couple questions for you cytokine...
Who are you and what qualifies you to run this fund?
I have run various different funds in "real life" and have been doing trading and investing for many years. You have only been registered here for a few weeks, use a tormail email, aren't verified on GLBSE.
Blame the regulators. Everything in the Bitcoin world is a legal grey area, especially if you're doing any sort of money management. That is why I use tormail. Are you selling blocks of shares at a discount?
I can probably sell you some IPO shares at a discount if you buy a large quantity, but I would have to put in the difference myself s.t. other investors do not lose NAV. Just PM me with how many shares you want and I'll let you know what I can do.

I think a well engineered long-short strategy not just reduces the risk, but also increases the expected return. "makes less money" means it will make less money in the best scenario. However, what we care about most is the expected average return rates, right? So both the "what if a meteor hits earth" condition, and the "if I long AAPL from the start" condition, contribute only a little to the average return rates.
Sorry, I should have been more specific, but with everything I say I must be careful not to give up my methodology. I have tested many long-short models and have found better performance from a long-only model that can switch into a completely different strategy during bear markets, albeit with higher draw-downs than a pure spread trader. So it's a tradeoff between return and draw-downs, just as it is with any approach to the market. But then again, perhaps this simply means I don't have as effective a pure long-short strategy as something you are familiar with.

I would go with multiple monitors - you can get a cheap USB box and attach many of them easily to a single computer. No expensive 3D cards are necessary since charts don't take a lot of crunching power - unless you're using HLSL to do real-time analysis or something like that.

Have you noticed the lack of huge dips now that Bitcoinica is out of commission?
Personally I think the price history of BTC/USD would be roughly the same with or without Bitcoinica. People too easily blame some ghost in the room, when the main driver of market behavior is just the great collective opinion of subjective and emotional people.
