I do agree that overtime (perhaps the next 50 years or so) many nations will have a digital currency in some form. And India can most certainly have its own currency. But the cryptocurrency that would be adopted by a nation as a whole would require input from some regulators within that country. No nation is going to simply adopt a currency created by some noname developer just because it has the name of the country in the coin.

ARK. I believe 2018 will be a breakout year for ARK. Wearable NFC devices, additional language support, foundation launch and more are all expected to hit late 2017 into 2018. IMO this is easily a $10+ coin.

ARK, XBL, WIC, ADX. NEO, SUB, Waves

SUB is announcing a burn coming on October 4th. This will be their 2nd burn.

This coin is valued so low and will always be valued low as long as there is no real use for it. Just because a coin has a nationality attached to it, it does not make it valuable. The coin must have a purpose and a usefulness for it to gain any real value. I do not even see any roadmap or potential for adaptation into real-world economy. Don't waste your money on this.
