- Barclays analysts say speculation in digital currency to spread of infectious disease
The rise of bitcoin has comparisons with the spread of an infectious disease, according to economists who argue the digital currency may have peaked in value as more consumers become immune to its appeal.
Analysts at Barclays said the soaring value of the digital currency last year, when prices rose by more than 900%, was helped by new buyers being “infected” by the euphoria surrounding bitcoin. The price has since crashed from almost $20,000 before Christmas to less than $7,000.
Using studies from the world of epidemiology – the branch of medicine concerned with the occurrence, distribution and control of epidemic diseases – the bank’s economists built a model for bitcoin prices that assumed more people were now “immune” to the lure of making money on the new financial asset.
What is bitcoin and is it a bad investment?
They said prices tend to rise when “infections” spread from one buyer to another, transmitted by word-of-mouth between friends – especially to those with a “fear of missing out” on a chance to get rich quick. The rate of new entrants to the market helps to set prices, while more people losing money will lead to immunity.
Arguing that the “susceptible” population for the bitcoin bug has now fallen, the economists said the peak reached just before Christmas was probably the ultimate price that could ever be achieved for the digital currency.
“This occurs with infectious diseases when the immunity threshold is reached; ie, the point at which a sufficient portion of the population becomes immune such that there are no more secondary infections,” the economists said.
Using that logic and applying it to the plethora of other digital currencies, including the peers of bitcoin such as ethereum and ripple, Barclays said the overall value for all crypto assets may never surpass $780bn – roughly equivalent to the peak sum of all cryptocurrencies in early January.
Attempting to value cryptocurrencies is problematic for the world of traditional finance, as they come as a new form of asset with no intrinsic value promised by cash flow. That means their value is solely determined by what people are willing to pay for owning them.
Economists had previously warned of bitcoin becoming a dangerous speculative bubble with worrying comparisons to the tulip mania of the 17th century, when bulb traders in Amsterdam lost vast sums of money betting on the plant’s value before prices crashed.
Barclays said demand for bitcoin had generally been from speculative buyers since about 2015, which was well before the meteoric rise for the digital currency last year. The bank said speculative bet making was probably at or near its end, due to enough potential new “hosts” having become alive to its risks.
