Minexcoin, Have you coinsider applying for coinmarketcap? This will give an idea, in real time, what the current marketcap of the coin is also the price per coin in USD. I beleive you need about $10K in volume in order to be accepted by coinmarketcap.
I believe coinmarketcap lists by exchange, because that's their first question when completing their online request form. Since Livecoin is already listed, they probably just need to reconfigure internally so MNX will show up.
