@Ilbilistenan - First, this coin isn't owned or run by one person or organization; it's decentralized like Bitcoin so its use cases are governed by what people want to use it for. Second, it's only listed on one exchange today, but with more validated use cases, I think the community believes it will naturally be listed on other exchanges.
Today, I can send NewYorkCoin to friends in France, Romania, Russia or Brazil, within seconds, who could decide to keep it or send it to an exchange to convert to another coin. That's just one use case that I can do now, whereas Stella Lumens needs to build it's network to accomplish what I can already do with NewYorkCoin.
Also, because NewYorkCoin's confirmation times are so quick, I don't need to wait around forever like I do with Bitcoin transactions.
But I'm not here to convince you to buy this coin; I'm a member of the community and I'm volunteering my time to provide updates. Do your own research and make your own investment decisions with any cryptocurrency that you may acquire.
