what is the advantage or difference while comparing with other cryptonight coins like monero, loki, sumokoin?
It's much more than just a coin. Take a look at the roadmap on the website. There will be mobile mining, a marketplace, decentralized exchange, and many more cool things down the road.
Seen all that before.
By the way, no wallet, no mining!
I'd give this a whirl just for fun, but project got to get their act together first.
