Delays in spot ETFs, a stronger U.S. dollar and growing regulatory pressure have all added to the crypto market’s underperformance this week.

Cryptocurrency markets fell this week, with total market capitalization falling 4.4% to reach the lowest since June 14 at $1.02 trillion. The movement reinforces Bitcoin’s market dominance as regulatory uncertainty hangs over the altcoin market.

Despite the hype surrounding recently filed ethereum and bitcoin exchange-traded funds (ETFs), the U.S. Securities and Exchange Commission (SEC) continues to delay decisions on these financial instruments. ETF delays have led to crypto investors choosing to wait and see.

There is also a lack of clarity on the legal status of ethereum, the largest cryptocurrency by market capitalization outside of bitcoin. Although the chairman of the Commodity Futures Trading Commission believes that ether is a commodity and not a security, there is currently no clarification from the SEC.
