213 votes keep going in right direction tommorow 1st place ?
Does the coin with the most votes get listed guaranteed or are there any further hurdles to take before a final decision is made?
No idea, they don't specify.
That's what I remember from this voting stuff on other exchanges. Your coin actually gets the overwhelming majority of the votes and in the end does not get listed anyway... I hope this is different here.
I think there is vote manipulation with some of the coins so exchanges might have to be careful there as well.
