Is Saitama, Inu the same as Saitama?

Excuse me, I'm a bit confused about something I came across. Could you please clarify for me whether Saitama, Inu is actually the same entity as Saitama, or are they two separate things? I understand that they both seem to be associated with the world of cryptocurrency, but I'm not entirely sure of the distinction between them, if any. Your expertise in this field would be greatly appreciated.
