Mark Dow is a hedge fund trader who previously served as an economist at the U.S. Treasury and the International Monetary Fund (IMF).
Within the crypto community, he is best known for opening a Bitcoin (BTC) short when the cryptocurrency was trading close to $20,000 in December 2017. It was its highest price range back then, but the economist was skeptical of its surge.

Within a year, Bitcoin crashed to $3,500 and Dow decided to close his short position in December 2018.
“I’m done. I don’t want to try to ride this thing to zero,” he told Bloomberg.
The blockbuster trade turned Dow into a legendary figure within the crypto community. Now, whenever he has something to say about Bitcoin, everyone listens.
A lot has happened after that monumental trade.
U.S. President Donald Trump emerged as a prominent voice of Bitcoin as Wall Street also decided to issue exchange-traded funds (ETFs) tied to the cryptocurrency.
Bitcoin eventually hit a new all-time high (ATH) of $126,080 on Oct. 6, 2025. But the flash crash only a few days later led to a downturn from which the cryptocurrency is still trying to recover.
Back in November, Dow reacted to the crash with a dig at maximalists like real estate mogul Grant Cardone, "You know how you know bitcoin is over? Grant Cardone is pitching it in his ads."
As Bitcoin crashed below $60,000 on June 25, he asserted that the high last year was indeed Bitcoin's top. The former economist slammed those who he claimed shill Bitcoin to retail traders and make quick exits themselves.
"No grifter left behind. Remember the ppl who made their bank trying to shill it to you."
This indeed was the top. No grifter left behind. Remember the ppl who made their bank trying to shill it to you. #bitcoinhttps://t.co/aZkUvQjqfr
