CryptoRubble is Russian government proposed digital currency. As this is yet to be confirmed I will give value to cryptorubble.com, .org. .net etc No potential use cases for cryptorubble cash IMO.
Agree totally with Ace3coiner. Too long. The "cash" at the end is too generic. I would advice staying away from speculating in the bitcoin space in this manner unless you find a high search, high PPC combo that could be attractive as a viable business development market.
