You are either going to vote or you are not, not sure what this believe is all about as you have no clue which one to vote  . First i will never vote for stable coins especially Tether because these stable coins cannot be trusted as the lies built by Tether are coming out now and there will be a time when the entire lies falls apart about the equivalent amount they pegged. So stay away from these trust less centralized coins as i am sure they will end up as a scam in the future.
Not sure they need to add any more coins as they have all the major coins accepted.
