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.

This is a perfect head start and i hope that several such villages can soon adapt this strategy to strengthen their economy
