September Curse Strikes Again? Dogecoin Cofounder Reacts as Markets Fall

September has begun on a familiar note for risk assets, with cryptocurrencies and other markets trading in the red. The ongoing drop in the market has sparked a reaction from Dogecoin co-founder Billy Markus, who goes by Shibetoshi Nakamoto on X.

"September starting great as always," Markus wrote in an X post, alongside a screenshot showing several assets, including the S&P 500 and cryptocurrencies such as Bitcoin, Ethereum, Solana, and Dogecoin in red.

In the last 24 hours, $361 million in crypto positions have been liquidated across the crypto market, according to CoinGlass data.

The Dogecoin co-founder's comment of "September starting great as always," amid a market selloff appears to be a tongue-in-cheek observation about the widespread red seen across the board.

September has historically been a poor month for financial markets, including Bitcoin and other risk assets.

Commonly referred to as "Rektember," September has been Bitcoin's worst-performing month on average since 2013, producing a loss of around 3% and only producing five positive monthly returns. The month of September is also a negative one for traditional markets. Since 1975, it has been the only month in which the S&P 500 saw a negative average return.
