WikiBit Exchange Runaway Risk Ranking #59: Zaif — Japan’s FSA License No. 00001 Makes It a “Living Fossil,” but Why Has Its Usability Nearly Fallen to Zero?

Founded in 2014 by Tech Bureau, Zaif obtained registration as a cryptocurrency exchange operator from the Director-General of the Kinki Local Finance Bureau under Registration No. 00001 on September 29, 2017.

The operating company was renamed CAICA Exchange Co., Ltd. in November 2021, but officially reverted to its former name, Zaif Co., Ltd., on November 1, 2023.
