CoinCycle is a social venture that provides efficient foreign coin exchange service for international travelers. Foreign coins are often left unused when travelers return home from abroad, which causes waste of valuable natural and economic resources. To resolve this social problem, CoinCycle is dedicated to advancing a foreign coin exchange system in order to restore the value of “forgotten coins” from abroad. With the wealth generated from the service, CoinCycle serves “forgotten people” from abroad, i.e., international refugees. Specifically, CoinCycle aims to help 3,000 refugees from North Korea, enhancing their living conditions in South Korea and helping them find their potential “left unused” through education and job search support.
