Can I use a logo off Google?

Excuse me, I'm curious about something regarding the usage of logos found online. Specifically, I've seen a logo on Google that I think would be quite suitable for my new cryptocurrency venture. However, I'm not entirely sure if it's permissible to just take a logo from a search engine like Google and use it for my business. Could you please elaborate on the legalities and ethical considerations surrounding this matter? I'd appreciate any guidance you can offer in this regard, as I want to ensure that I'm adhering to all necessary regulations and best practices. Thank you for your time and assistance.
