What is Coinbase ETF & how does it work?

Could you please elaborate on the Coinbase ETF? I'm curious about what exactly it is and how it functions. Does it provide exposure to a diversified basket of cryptocurrencies? And how does the ETF manage the risks associated with the volatile nature of the crypto market? Also, what are the fees associated with investing in this ETF, and how does it compare to other investment options in the crypto space? I'm interested in understanding the pros and cons of investing in the Coinbase ETF and how it could potentially fit into my investment portfolio. Thank you for your assistance.
