This site is a project derived from the YouTube channel "Bitcoiner's Hanseikai," which deeply discusses specialized topics on Bitcoin, and "DH Magazine," a newsletter distributed by Diamond Hands, the largest Bitcoin-specialized company in Japan.
Our goal is to create a site that is easy for Bitcoin beginners to understand and to further promote Bitcoin within Japan. We are also concerned about the abundance of misinformation reported in recent media and social networks. Under the supervision of experts deeply involved in Bitcoin-related businesses, we strive to disseminate accurate information.
