Is the nextexchange a good one? I even couldn't find it on coinmarketcap. Why it's important to get 500 votes?
As written, from 250 they start negotiations.
I don't think next exchange has been launched yet but they will soon. They are still in the voting phase to know which cryptocurrencies they will have listed on their exchange. I hope the next exchange isn't the one that the Hacken team have been talking about to get listed next. I am waiting for Binance.
