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.
You can mine to the telegram wallet for now then move coins once devs fix gui wallet issues. Or compile the cli wallet. Those who are willing to put in the work early are the ones who are rewarded the most. Those who sit on the sidelines end up regretting it. Good luck.
