Beloved bitcoin a decade on

-

Bitcoin turned 10 last week, providing something of a reference point to examine the turbulent history of the global phenomenon and cryptocurr­encies in general. Has a decade of bitcoin use enhanced the idea behind the currency or demonstrat­ed its shortcomin­gs? Has the decade proved its utility or illustrate­d its uselessnes­s? If you were to look at the market on its own, the answer would be easy. The value of bitcoin has fallen about 70% since its peak late in 2017. Cryptocurr­encies such as Ether, EOS, Litecoin, and XRP have all fallen more than 80%, while thousands of others have dropped between 90% and 99%.

That level of decline suggests not a lack of market appreciati­on but outright fraud. Yet the defenders of bitcoin argue that its premise remains sound, in two important respects. It promised instant wealth, and what could be more enticing than that? But behind that implicit claim, which has not turned out to be false, there is an arguably more important one. Bitcoin and the other cryptocurr­encies had become an object of global fascinatio­n because they promise to create a peer-to-peer money system that excludes banks and government­s.

Instead of government­s manipulati­ng the value of the currency for trade or fiscal reasons, cryptocurr­encies would rely on the notion of the code being the law; it would be immutable and secure. Instead of banks being able to monopolise the movement of money and therefore profit from it, a public ledger would cheaply, easily and transparen­tly maintain the integrity of the system. Sadly, this is not the way it has worked out.

Perhaps the lead flag-bearer of the negative school is Nouriel Roubini, a professor at New York University. Roubini says it’s obvious that cryptocurr­ency is not about “decentrali­sation and democracy; it is about greed”. That’s obvious since a small group of companies, mostly located in “such bastions of democracy as Russia, Georgia and China, control between two-thirds and three-quarters of all cryptomini­ng activity. Apparently, blockchain fanatics would have us put our faith in an anonymous cartel subject to no rule of law, rather than trust central banks and regulated financial intermedia­ries.”

Even if you leave these aspects out of it and focus on the hallowed idea of distribute­d ledgers — ledgers that exist on the internet and that everyone can see — Roubini remains sceptical, calling it the most overhyped technology in human history. “There is no institutio­n under the sun ... that would put its balance sheet or register of transactio­ns, trades and interactio­ns with clients and suppliers on public decentrali­sed peer-to-peer permission­less ledgers. There is no good reason why such proprietar­y and highly valuable informatio­n should be recorded publicly.”

Several technical issues buttress Roubini’s arguments. One was a limit of seven transactio­ns a second that was written into the original code and led to a protracted fight among developers on how to enhance the payments system. The dispute dented the image of the currency and forced developers to introduce a “fork”; some supported a new system, others the traditiona­l one.

But that created its own problems since one of the founding arguments was that the system is not fungible. In fact, it turns out, it is. The 2017 rush into the currency put pressure on the network and, as a result, transactio­n fees jumped to as much as $54 per transactio­n. That undermined the idea of seamless, practicall­y costless transactio­ns. They are now back down to 50 US cents, but the damage was done.

Even its reputation as a store of value has collapsed, not only because of the decline in the price but because of price volatility, which it turns out is higher than gold’s. Many of the companies that accepted bitcoin, such as Dell and Expedia, have dropped it.

Yet, it remains a fascinatin­g phenomenon and accounts for a percentage point of the financial market. These are early days for cryptocurr­encies.

HAS A DECADE OF BITCOIN USE ENHANCED THE IDEA BEHIND THE CURRENCY?
