Five predictions for (Bit)coin

Contributor Tom Geller writes: "I recently wrote an article about Bitcoin and the law for Communications of the Association for Computing Machinery. In researching it I ran into plenty of wishful thinkers, ridiculous greedheads, and out-and-out nutbags promising a rosy future. I also found the expected blowback from vehement naysayers who think the best way to combat crazy is with more crazy. But despite that, I walked away believing that Bitcoin — or a decentralized cryptocurrency like it (let's call it "Coin") — is here to stay. As an interested outsider to the Coin economy, and a long-time technology commentator, here's what I think its future holds." Read on for Tom's predictions. Coin's primary use will continue to be in international transactions.

While people wonder "When will I be able to pay for groceries and utilities with Bitcoin?", that use might never come. But Coin already shines in international transactions, where it provides a clear advantage over current systems, which are expensive and complicated hassles. That's why PayPal has become the go-to solution: it just works, albeit with typical fees around 3-5%.

Coin reduces that fee to a small fraction of 1% (when sent directly), and is available in places where PayPal fears to tread (Zimbabwe, Pakistan, etc.). Coin transactions occur instantly, with no intermediary, and — for better or worse — without recourse.

That leads to Coin's second primary use: to store liquid value in places where other stores (such as national currency) are unreliable. For all the cries that Bitcoin is "unstable", it seems to have settled quite nicely after its April spike. Certainly it looks appealing to anyone in an unstable country, and it's even tempting for those in places where the currency's been on a long, slow slide, like Argentina.

Coin's big vulnerability is its interface with national currencies ("real money").

None of this matters if you can't get your money out again. And that's where governments are taking a close look at Coin — with good reason. First, Coin exchanges have a terrible track record; second, such points of exchange are bottlenecks through which financial crimes often flow.

In the U.S., the government's Financial Crimes Enforcement Network (FinCEN) issued guidance asserting its right to regulate "Money Services Businesses", and defining exchanges dealing in virtual currencies (including Bitcoin) as such. That's a problem for many existing Coin exchanges, as the costs for complying with regulations are high. But if there's not a stable and reliable way to get national currency in and out of Coin, its value will plummet.

Conversely, Coin's value is likely to shoot up if this interface gets easier. Right now, it's surprisingly hard to buy Bitcoin (et al.) directly with U.S. dollars. Most methods require bank wires, tricky multi-step workarounds, and high fees. (I found Coinbase to be the most accessible, albeit with long delays and a bank verification procedure similar to PayPal's.) If Coin becomes as easy to buy as a gift card and redeemable at every bank, its practical utility will soar for everyday people.

No government will make Coin illegal.

Despite bloviation by a few politicians and baseless statements in the press, Coin is not per se illegal, and there have been no serious attempts to make it so. The FinCEN guidance mentioned earlier explicitly says that ordinary users — those who buy and sell using Coin — are "not subject to FinCEN's... regulations for MSBs". It's possible that other government agencies will continue to claim authority, but there doesn't seem to be much support for it.

A lot of noise has been made about Coin's use in illegal business, for example on Silk Road (where it's the only currency). But law enforcement is realizing that the currency isn't to blame, much as they've started to say that Craigslist isn't responsible for crimes organized through its ads. I predict that that distraction will continue to surface from time to time, but will essentially die soon.

Even if governments attempt to illegalize Coin, there's only so much they could do to criminalize ordinary users. Again, Coin's real vulnerabilities are higher up the chain. However....

If Coin succeeds, governments will get involved — for the better.

"Noooo!!!" scream the cryptoanarchists who are Coin's pioneers. "Keep the government out of this! Coin can't be controlled! Nobody can take away our freedoms!" What they don't realize is that this attitude doesn't reflect the values of Coin's future users. The benefits of "freedom" matter to the innovators; convenience and safety matter to those who follow.

"Government" in this case could also be a government-size corporation, syndicate, or other entity. The important thing is that it's big enough to administer, back, and enforce initiatives to protect the Coin economy. Whatever that "bully entity" is, Coin adopters will welcome it because of two major flaws currently in (Bit)Coin's design.

First, Coin is ridiculously easy to destroy by accident. If you lose the private cryptographic key that identifies your coin, it's gone. Not just stolen, but removed entirely from the economy, so nobody will ever own it again. Consider these stories on Bitcointalk.org, where within a few messages the cumulative total tops 10,000 BTC — currently valued around a million dollars. A central authority could address this in several ways such as tracking, restitution, etc.. People don't care that their cash is anonymous when the rent money disappears.

Second, the entire system is vulnerable to a brute-force attack. Without getting into the specifics, Coin (well, Bitcoin) works because it assumes that at least 50% of the computer power on the network is held by honest players. But a recent 51% attack on Feathercoin (a Coin with much lower capitalization) showed that it's possible for a single party (or syndicate) to trump that.

Let's do the math for Bitcoin, the Coin with by far the highest capitalization, at just north of USD$1 billion (1 x 10^9). To reliably overwhelm the network, you'd need computing power delivering about 100,000 gigahashes per second. Computers optimized for Bitcoin processing are currently available for about $1,000/gigahash, so sufficient computing power can be bought for $100 million. Electricity cost for the deed would be about $200,000/day.

O.K., it's not something a basement hacker could whip up. But there are over 400 people, and thousands of syndicates with a billion dollars in the U.S. alone. Perhaps at least one of them is crazy enough to drop 1% of the wealth to partially control (or completely destroy) a billion-dollar system. (Hell, one of them recently spent 1/10th of that price tag on his wedding.)

Those are only the two biggest technical concerns. Then there's the galaxy of financial services (such as insurance) that's available for fiat money, but which would be hard or impossible to provision for Coin without a central authority. Time could overcome these barriers; a bully entity would overcome them faster, and with greater public buy-in.

Bitcoin is not the end game.

Along those lines, I don't believe that Bitcoin will be the ultimate winner in this game. It's the 1.0, and a brilliant first effort at that. But it's not perfect, and several pretenders to the throne already claim to fix some of its bugs. In fact, shifting conditions may require periodic issuance of new Coin as a matter of course. (As I said before, I believe such issuances will involve a central authority.)

These predictions all assume that Coin will grow, and there are many reasons it might not. However, I'm bullish on it for the long-term. It's already proven its value in use; the public is used to handling Coin-like money (viz. Square Wallet); and its first major hurdles are in the past. Now it's ready to enter a fascinating future.

    Addressing concern numbe 1: (income tax)...
    Bitcoin income is taxable just as barter "income" is taxable. To date this has been a small problem, because when you sell your bitcoin to buy a loaf of bread that transaction comes under scrutiny, and at this point in time, that transaction is the only bit the US government really cares to regulate (as mentioned in the story).

    However, when you can buy many things with bitcoin, and it becomes very liquid, you can expect more forms of reporting required by the IRS, because bitcoin income, sans reporting, becomes totally off-the-books income. But for that to be a problem, bitcoin has to become just about as liquid as dollars or euros.

    If large bitcoin receipts were reported as miscellaneous income, or barter income on your tax forms, valued at the then-current exchange rate, you will have removed any reason for the US government to be concerned about this as far as your personal tax return. It would be just like Tips reported by waitresses. No way to prove it, but mighty suspicious if you say you wait table for a living and don't report tips.

    The US government has no interest in making transactions more expensive, or adding any friction to the system.
    They do have a vested interest in knowing about income in the form of bitcoin just as they have an interest in knowing about Paypal income.

    For all the cries that Bitcoin is "unstable", it seems to have settled quite nicely after its April spike.

    That's the one that got me. Two months where the price only fluctuated by less than 40% does not a pattern of stability make! There is no trend on this chart that leads me to believe it's ever been any more stable than the Iranian Rial.

    Bitcoin, itself, will remain a niche currency. The author's point about places where banks fear to go is good. Otherwise, the built-in deflationary tendency will make it increasingly irrelevant in the larger economy.

  18. Re:The 51% attack is fatal by fireteller2 · · Score: 2

    It is not fatal by any definition of fatal I'm aware of. To the degree it has any effect at all it is only in terms of the current and ongoing transactions for the duration of the attack. To fit some definition of fatal the attacker must maintain the attack indefinitely, the attacker must also be able to respond to any effort by 'honest nodes' adding additional computing resources in response (i.e. there is a counter attack), and the existence of the attack is detectable and locatable.

    Anecdotally the current hash rate is greater then the combined resources of all known supercomputers in existence today, so there is no plausible argument that we are discussing 'one user'. If anything we are talking about a state actor, with unimaginable resources, and to such a state actor other attacks are far more efficient. For example a public opinion war, such as what you are trying to wage.

    In that this is fatal, it is because of usability, and functionality not cryptography. In other words it is exactly not "fatal, at least from a cryptographic standpoint." In this scenario there is no compromise of the cryptography in any way at all. This is precisely the type of misinformation I am trying to prevent in my post.

    Also, "lack of security definition" has no meaning in this context so I'm at a loss for what you are trying to say there.
