How much is mega EV?

Excuse me, could you please clarify what you mean by "mega EV"? Are you referring to a specific cryptocurrency or a unit of measurement related to electric vehicles? If it's a cryptocurrency, I'm not familiar with one named "mega EV" as of my knowledge cutoff. Could you provide more context or correct the term if I've misunderstood? If it's related to electric vehicles, then "mega EV" might not be a standard unit of measurement, and I would need more information to accurately answer your question.
