Has COVID-19 Helped or Harmed Crypto and Blockchain?

Cryptocurrencies rebounded after an initial slump earlier this year

The recently aired discussion at COSM about the future of bitcoin and other privately minted cryptocurrencies took place last October, before COVID-19 was much thought of in the Western world. Catching up, the cryptos and blockchain had a rough ride earlier this year but they have stabilized recently. In February, as the pandemic sent markets scurrying, things were looking grim for the cryptos: During the last week, the spread of the coronavirus has been all over the news; the virus, which had remained well-contained in China, spread throughout South Korea, Iran, Italy, and is now reaching its fingers into other parts of Europe.

The Stock Market Keeps Rising Despite COVID. Is It Nuts?

I’ve been asked whether advanced AI can explain the conundrum

What is going on? Our GDP has collapsed and 16 million people are unemployed.

That’s what happened during the Great Depression when stock prices fell 90 percent and the unemployment rate averaged 19 percent for a decade.

Beware of Geeks Bearing Formulas—It’s Often Pseudoscience

Pseudoscience based on data without theory and theory without data undermine the credibility of real science, which is the key to human progress

Elsewhere I have warned of the perils of making decisions based on data without theory. For example, the patterns discovered by data-mining computer algorithms are often nothing more than meaningless coincidences. It is also perilous to go to the opposite extreme—to make decisions based on theory without data. Once upon a time, for example, economists were fond of sketching labor demand and supply curves and assuming that the economy was at their intersection. That is, labor demand is equal to supply, so that everyone who wants to work is working. The unemployed have chosen to be unemployed because they value leisure more than income. True believers were fond of this theory and little troubled by reality. Between 1929 and 1933,…
