What email service is best for wallet, exchanges, etc.? Google or another service? Can it by my main email address that I use for most email, or is it better to create an address specifically for crypto trading?
Well, any email account should work fine but it’s often better for privacy and convenience reasons to separate different activities to different emails. Of course, all your online accounts should have different, strong passwords – I recommend using a password manager to achieve this without having to remember or record numerous passwords.
I like Protonmail.ch and Tutanota.com a lot more than Google as these companies have greater respect for user privacy.
