Qualities of a good moderator

Please, I don't know if this is the best place to make the Post.
Kindly bear with me if it is not.but I care to know.
What's are the qualities a good moderator must possess.
I felt he/she should be of a high rank, at least hero member.
He or she should not be temperamental, so as not to penalize people on aggression,must not be easily provoked because everyones capacity here is different.
He/she must also not be biased,must not be a racist because Cryptocurrency is for every nation and tribe.
What's your own opinion?
