This is a cryptospace where physical contact is very rare, there is no reference to a crypto address whether the owner is male or female which means it really isn't a necessity. Maybe the statistics about gender numbers are true, but we will never know the reality. I have a female friend who is active in several airdrop groups, and people there call her "sir", "bro", "man" even though she is clearly wearing a profile photo of her own face.
So, gender isn't something serious.
