Bitcoin is not a Hedge Against Tail Risk

Claims that bitcoin is the new “digital gold” are feeding a new bubble in it and other cryptocurrencies. The last one in 2017-18 saw bitcoin go from $1,000 to $20,000 and then fall back to $3,000 by the end of 2018.

Since the fundamental value of bitcoin is zero and would be negative if a proper carbon tax was applied to its massive polluting energy-hogging production, I predict that the current bubble will eventually end in another bust.

Referring to bitcoin or other crypto as “currencies” is a misnomer. They are not a unit of account: virtually nothing is priced in them. They are not a scalable means of payment: with bitcoin you can do five transactions per second while the Visa network does 24,000. Bitcoins are barely used by legitimate companies as payment for goods and services, although Tesla said it planned to start accepting them.
