But the thing is, short term, it's going to be hard to convince people to put a large sum for BTC when it can move 40% either way in 2 days. People don't want to deal with this kind of preoccupation in their day-to-day life. As it stands, prices won't be decided any time soon in BTC unless it keeps some kind of stability against major currencies or commodities. This is a massive barrier for adoption.

"Pirateat40" Makes Off $5.6M USD in BitCoins From Pyramid Scheme
Jason Mick (Blog) - August 28, 2012 4:11 PM

Bitcoin investors fall for classic Ponzi ploy

Bitcoins, everyone's favorite quasi-legal internet currency, are still lingering around thanks to strong support from the hacker, future, and technopunk communities. Prices remain off their record highs, but at $10.97 USD per Bitcoin at last count [source], the currency has legitimate value.

The first rule of Bitcoins is to guard your digital treasure wisely. After all, the currency is denationalized, and has no central governmental regulators (though blatant fraud attempts are combatted by the community). Bitcoins are oft stolen from those who don't strongly encrypt their wallets. Thus most experienced Bitcoin users exercise a healthy degree of caution when storing and spending their hard-earned digital cash.

That makes the strange and sordid tale of the Bitcoin Savings & Trust and its originator "pirate40" all the odder.

Apparently, a number of Bitcoin users were lured to invest their Bitcoins in this digital hedge fund, which promised lucrative payouts. But like many things too good to be true, it probably was -- BS&T is being billed as a "pyramid scheme" and reportedly pirateat40 has pulled a Bernie Madoff and made off with 500K worth of Bitcoins ($5.49M USD).

Last week pirateat40 sought to assuage concerned investors, writing, "Once my process is released you'll understand more of how coins move around."

But this week pirateat40 did offer a vague sort of explanation that sounds kind of like an admission that the fund was pyramidal in structure:

The decision was based on the general size and overall time required to manage the tras*actions. As the fund grew there were larger and larger coin movements which put strain on my reserve accounts and ultimately caused delays on withdraws and the inability to fund orders within my system. On the 14th I made a final attempt to relieve pressure off the system by reducing the rates I offered for deposits. In a perfect world this would allow me to hold more coins in reserve outside the system, but instead it only exponentially increased the amount of withdrawals overnight causing mass panic from many of my lenders.

The fund's chat room has an away message from the boss commenting "When I know, you will."

Upset investors are flocking to Bitcoin boards crying a common tune -- "WHERE ARE MY BITCOINS?"

Initially BS&T claimed the 'coins would arrive with interest in just a week. Now it comments that there is "no ETA on payments." While there are many losers in the scheme, some investors who got out in time actually gained; after all, like most Ponzi schemes BS&T initially attracted attention by paying out large amounts of interest to early adopters before reaching critical mass and imploding.

Some duped investors have taken to trying to hunt down the pesky pirateat40. There are rumors that he is based in Texas. But short of extracting some good old fashioned (and wholly illegal) vigilante justice, it's unclear what the scammed can do. Bitcoin Ponzi schemes are growing more frequent -- one lawsuit in California [Scribd] has already taken up the issue. But it remains to be seen how seriously the courts will take the cyber-currency, given that it's founded on a rather anti-nation premise.

And of course, the onus for these losses largely rests on those who sent someone named "pirateat40" actual money, and failing to recognize the classic signs of a Ponzi scheme -- inflated interest rates, shadowy management, and unrealistic promises.

Hacker steals $250k in Bitcoins from online exchange Bitfloor
Irreversible tras*actions make Bitcoin security a high-stakes business.

by Timothy B. Lee - Sep 5, 2012 1:20 am UTC

The future of the up-and-coming Bitcoin exchange Bitfloor was thrown into question Tuesday when the company's founder reported that someone had compromised his servers and made off with about 24,000 Bitcoins, worth almost a quarter-million dollars. The exchange no longer has enough cash to cover all of its deposits, and it has suspended its operations while it considers its options.

Bitfloor is not the first Bitcoin service brought low by hackers. Last year, the most popular Bitcoin exchange, Mt.Gox, suspended operations for a week after an attacker compromised a user account and sold all of his Bitcoins in a firesale that temporarily pushed the price down to zero. The site survived the attack and remains the leading Bitcoin exchange today. Hackers made off with another $228,000 in Bitcoins from online services earlier this year.

Bitcoin's peer-to-peer design means that tras*actions are irreversible. Once a tras*action appears in the blockchain, the global record of Bitcoin tras*actions, no one has the authority to reverse it. And the pseudonymous nature of Bitcoin makes it difficult to trace stolen Bitcoins to their new owners.

Some regard irreversible tras*actions as a key Bitcoin antiestéticature, since it means merchants never have to worry about "chargebacks." But this "antiestéticature" also dramatically raises the security stakes. Anyone who deals in Bitcoins, from complex exchanges to ordinary users have to worry about hackers making off with their cash. Indeed, malware that steals your Bitcoins automatically has been spotted in the wild.

In a June interview, Bitcoin developer Gavin Andresen told Ars that his team is working on a new antiestéticature called multi-signature tras*actions that could reduce the vulnerability of Bitcoin wallets to this kind of attack. Under this scheme, a user's signature is divided among multiple devices, all of which would need to approve a tras*action before it could be accepted by the Bitcoin network. For personal users, that might miccionan splitting the key up between a PC and a smartphone. For online Bitcoin services, it would miccionan splitting control of a Bitcoin wallet among multiple servers. Under that scheme, hackers could only steal Bitcoins if they succeeded in compromising all of the servers holding portions of the private key.

But at least until these new techniques mature, it's wise not to entrust large amounts of Bitcoins to third-party services, even those with excellent reputations. And always encrypt your Bitcoin wallet as soon as you're done using it.

Disclosure: The author owns some Bitcoins, and has so far avoided having them stolen by hackers.
