Wallet will be released on 14th March 21:00 UTC, not 18 March.
Download links will be available at https://ringcoin.tech/
Two trading sites are confirmed where we can trade Ring
http://coxi.io is the first exchange that confirmed support for RNG.
They will reward RNG to the holders of BTC, DASH, LCC and DOGE at the time of snapshot and RNG will be traded on their exchange with:
ETH, BTC - Crypto pairs
PLN, EUR, USD - Fiat pairs
2nd exchange is https://www.nlexch.com
This is the kind of project worth working in, the project or the platform is not yet launch but there are already two exchanges that are willing to trade it there, much better than crowdfunding some crowdfunding based cannot even take their coin in even a small exchange but project like this can easily get in.
