A small japanese village named, Nishiawakura is making their economy much more beneficial with the help of cryptocurrencies by launching a Initial Coin Offering. I think it is a best way to help some small villages to grow up with really good profits and also it might bring the cryptocurrencies some more close to legalisation.
The village is home of approximately 1500 villagers and and they unveiled their plans to launch a regional initial coin offering.

In my own opinion, cryptocurrency can really help an entire country to improve their own economy, if cryptocurrency will be legalized by the government then there will be more people who can actually have their own job and being a jobless is not a problem anymore since you can become a trader or advertiser of an ico.
