Rivalries arise, try to take their spot on against world leading Crypto projects by offering what others have failed to offer more maximally. The reason for the Ros coin project to be built was to rival other cryptocurrencies in speed of transactions coupled with low transaction fees. Built as a mainchain token for the Luniverse project which allows the building of sidechains, the project coin was able to leverage that technology to its use, bringing transaction fees to a bare minimum and speed was very appreciable. One thing the project failed to achieve though, was it's quest for dominance. The project faced a lot of backstabs to its progress, listed on only one exchange and trading volumes ever reaching a good value, the project developers abandoned ship ⚓.
It's website is not working anymore. What's worse is the fact that it's mainchain provider got its last transaction listed 193 days ago. Currently, Ros coin is listed on just one exchange, trading at half a cent with the daily volume barely touching a dollar value. With no working explorer, I don't see any reason why you should buy this coin.
