Where can I buy an ethfi coin?

Could you please guide me on where I might be able to purchase an ethfi coin? I've been hearing a lot about it recently and am quite interested in adding it to my portfolio. Is there a specific exchange or platform that offers this coin? Also, are there any special considerations or requirements I should be aware of before making the purchase? I'd really appreciate your help in navigating this process. Thank you in advance for your assistance.
