The U.S. Clarity bill, a cryptocurrency market-structure proposal, failed to clear a Senate hurdle, putting the spotlight back on regulatory uncertainty surrounding Coinbase. The bill did not secure the 60 votes needed to open floor debate on Sept. 16, Cointelegraph reported. After the vote, shares of Coinbase, Circle and Strategy fell 5 to 10 percent and remained weak the next day. Analysts also differentiated impacts across firms, while tokenisation expectations, staking-driven returns and security concerns around AI drew attention.

Phemex CEO Federico Variola said artificial intelligence has been broadly negative for the cryptocurrency industry, arguing it is drawing liquidity away and strengthening malicious actors through social engineering and vulnerability discovery. He said rising threats could make it harder for small protocol teams to operate without large cybersecurity budgets and could reduce the appeal of self-custody and decentralised finance. Others cited both risks and defensive uses for AI.
