A derogatory word for someone who is not technical, yet wants to talk to you about "blockchain" and related technologies ad nauseam, usually as a tactic to soundsmart and relevant.

A person who spends all of his free time trolling, scamming, and producing smear campaigns on social networks against groups and individuals or Cyber Cancer.
