For me, this AMA thing means absolutely nothing, it makes absolutely no difference except for the fact that community members and investor s get to see the founder or founders of the project speaking live which kind of builds trust for the project to some certain level, aside this, I don't see any other benefit it brings cus whatever they will be discussing or talking about, I've already read in the whitepaper and anything I don't understand, I've asked in the community group and possibly gotten an answer.
And besides, what's the use of an AMA when they don't actually answer all the questions they are asked,? They choose ones to answer and others, they ignore, doesn't make any sense to me.
