It's an @coinbase.com address, it seems is not phishing at least.
Do you know that sending addresses can be faked too, right?
Err.... Is this true? Can the sending addresses be faked? I'll be in big trouble. I have always trusted the emails coming from by official Bank email.
there is an official email for example something like "support[at]coinbase.com" this cannot be fake the fake Email would be like this" "support@[similar fake address like coinbase].com" like coiinbase
No, wrong. Email can be faked by editing the header of the email. They however, can't change the IP or domain which the email originated from. They would most probably end up in your spam folder(for gmail). Always check the headers of the email to identify the authenticity of the email.
