One of the world’s biggest bitcoin exchanges, the Tokyo-based Mt. Gox, has stopped trading indefinitely; potentially risking millions of dollars belonging to investors betting on the digital cryptocurrency. 

Mt. Gox website: In light of recent news reports and the potential repercussions on Mt. Gox’s operations and the market, a decision was taken to close all transactions for the time being in order to protect the site and our users. We will be closely monitoring the situation and will react accordingly.

Mark Karpeles, CEO of the company, has resigned from the Bitcoin Foundation’s board as well. MtGox Co. Ltd. operates the website, and is a subsidiary of Tibanne Co. Ltd.
