Bitcoin Does Not Protect Against Fraud

There is a common misconception that the cryptocurrency Bitcoin is safe and secure and will protect those who trade in it from fraud. However, NEP’s Bill Black explains, Bitcoin is just as susceptible to fraud as any other type of transaction and complacency makes the likelihood of fraud only greater.

Bithumb: Hackers ‘rob crypto-exchange of $32m’

This article from the BBC. NEP’s Bill Black has warned about these issues…

A leading crypto-coin exchange has halted trade after declaring that hackers had stolen some of the digital currencies it stored.

Seoul-based Bithumb said that 35bn won (£24m; $31.6m) worth of cyber-cash had been “seized” overnight, adding that it would fully compensate affected customers.

The values of Bitcoin, Ethereum and Ripple all fell on the news.

It is the second time in less than a year that Bithumb has been breached.

Last July, it acknowledged an employee’s PC had been hacked – exposing users’ personal details.

South Korea’s spy agency later accused North Korea of being responsible after the stolen information was used to carry out scams.

Bithumb notified a local regulator – the Korea Internet and Security Agency – of the latest attack, shortly before alerting the public via social media.

Bitcoin Frauds Keep Growing

By William K. Black
June 18, 2018     Kansas City, MO

One of the prime myths that white-collar criminologists have to refute repeatedly is that blockchain makes fraud impossible.  Blockchain, in some settings, is a costly means of making some frauds much more difficult.  Blockchain is useless against the most important frauds.  The primitive worship of blockchain as a supposed garlic capable of warding off evil breeds complacency, and complacency produces increased fraud and greatly extends the life of fraud.

The difference between making fraud impossible and (in a few specialized settings) ‘much more difficult’ brings to mind the critical difference explained in The Princess Bride between ‘dead’ and ‘mostly dead.’  Blockchain is useless in stopping, for example, any or the three epidemics of ‘control fraud’ that drove the 2008 financial crisis and the Great Recession.  Lenders’ executives extorted appraisers to inflate appraised values of homes, creating a Gresham’s dynamic in which bad ethics tends to drive good ethics out of the markets and professions.  The second fraud epidemic in loan origination was ‘liar’s’ loans, which were designed to aid lenders and their agents to inflate the incomes of borrowers.  Note that both of these primary fraudulent loan origination schemes involve lenders deliberately seeking to provide false (inflated) data designed to inflate the market value of homes.  The third fraud epidemic that drove the U.S. financial crisis was the fraudulent sale of these mortgages to the secondary market through false “reps and warranties” about loan underwriting – principally the fraudulently inflated appraisal values and borrowers’ incomes.

Bitcoin System: Some Additional Problems

By Eric Tymoigne

In my last post, I argued that the fair price of a bitcoin as a monetary instrument is zero BTC; a bitcoin contains no promise in terms of income, in terms of convertibility, in terms of maturity, or any other. As a commodity, I have no idea what its fair price is. BOA says it is $1300. I will let those who find utility in the bitcoin payment system and speculators decide how much they are willing to pay in USD for a number credited on their screen in BTC. All I can tell you is: “money does not grow on trees.” Money is not a natural occurrence, it is a man-made financial devise. It looks like the bitcoin creator’s views on money were shaped by the old and erroneous idea that “gold is money.” Gold was at best a collateral embedded in a monetary instrument (gold coin), the metal itself was never money. In today’s blog, I will focus on three other issues with the bitcoin system that prevent it to work well as a monetary system. While I explain what ought to happen to make the bitcoins work properly as a monetary instrument, I am not sure it can be done.

The Fair Price of a Bitcoin is Zero

By Eric Tymoigne

The virtual currency craze is on a tear, with new virtual currencies emerging every day. The New York Times just ran a series of articles about them last week. “Charles Ponzi would be so proud!” one person appropriately commented at the bottom of this article.

Before going any further, let’s learn a bit more about the bitcoin system (also here and here). There are three components to this system:

–       A unit of account—the Bitcoin (BTC)—in which all transactions are recorded and goods and services are priced.

–       A payment system, supposedly secured and anonymous.

–       A means of payment—bitcoins—that is needed to complete all transactions in the payment system (there are coins of several denominations and the coin with a face value of one BTC is called the “bitcoin”).

Given the craze over bitcoins, their price in US dollars (USD) has soared with a BTC 1 coin going for as much as USD 1200 at one point, leaving Business Insider’s Joe Weisenthal saying:

“At this point, I have zero idea what a ‘fair’ price for Bitcoin is.”

I have an answer to that question, but before I reveal it (pretend you did not read the title of this post), let’s spend a bit of time getting to know the Bitcoin, starting with its payment system.
