Can I use Gmail instead of email?

I understand that you're curious about whether Gmail can be used as a substitute for traditional email services. May I inquire if you're asking specifically in the context of cryptocurrency and finance transactions? Gmail, as a popular email service provider, certainly offers functionality for sending and receiving emails, but there are specific considerations when it comes to security and privacy in the cryptocurrency and finance industries. Would you like me to elaborate on those points, or are you interested in exploring other aspects of using Gmail for these purposes?
