"Literally no reason" in this case meaning...?

If you went through 7 books of "Harri Potter" carefully written to never reveal the gender of the main character, would you care?

It's human nature to be curious. And particularly about a dark shady character pulling of crazy crypto heists.

Ambiguity over the identity of the narrator is part of the hook. Of course it's reflex to start drawing a picture of this character in your mind as you read. When the gender is unknown or not clear, and particularly when you throw in mixed messages that this might not be the stereotypical male basement dweller, it's interesting.
