Japanese Cryptocurrency Exchange Zaif to Resume Activity Seven Months After Hack

Japanese cryptocurrency exchange Zaif announced that the transfer of the exchange will become effective on April 22.

Japanese cryptocurrency exchange Zaif announced that the transfer of the business from Tech Bureau to Fisco Digital Asset Group (FDAG) will become effective on April 22, and that normal activity will resume on the next day. Cointelegraph Japan reported on the developments on April 20.

Bitcoin (BTC), bitcoin cash (BCH), and monacoin (MONA) were stolen from the exchange in a hack in September last year, resulting in total losses of cryptocurrencies worth 6.7 billion yen (around $59.8 million). With the acquisition, which is a part of the user compensation plan, FDAG provided financial support of 5 billion yen (over $44.6 million) to Tech Bureau and acquired a majority of the company’s shares.

As Cointelegraph reported in October 2018, the sale of the exchange is part of the plan to compensate the users who lost Monacoin in the hack after the sale of the business. The users will be repaid 40% in fiat currency and 60% in crypto. The rate of compensation will be 144.548 yen ($1.28) per MONA which will become available for withdrawal on April 23.

In mid-March, an 18-year-old hacker was referred to Japanese prosecutors for stealing cryptocurrency after allegedly breaching Monappy, a digital wallet which can be installed on a smartphone, and stealing 15 million yen (over $134,000) of cryptocurrency.

Japan: Zaif Exchange Reports ‘Glitch’, $20 Trillion in BTC Temporarily ‘Purchased’ For 0 Yen

Japanese cryptocurrency exchange Zaif has admitted a “system glitch” allowed customers to temporarily ‘buy’ trillions of dollars worth of Bitcoin for free last week, local online journal The Asahi Shimbun reported Wednesday, Jan. 21.

Zaif informed users about the glitch in a post on their site Tuesday, Jan. 20, explaining that for 18 minutes on Feb. 16 users accidentally found themselves able to ‘trade’ yen for virtual currency  — at an exchange rate of 0 yen per coin.

Asahi Shimbun reports that seven users where able to obtain crypto for “free”, but the exchange managed to cancel all illicitly-gained transactions.

Asahi Shimbun reports that one “buyer” made an attempt to sell 2,200 trillion yen (about $20 trillion) in Bitcoin before the problem was resolved.

Zaif’s Twitter posts reveal further criticism from users, who complain about poor backend performance and lack of support.

The latest difficulties comes as Zaif gains increased regulatory scrutiny in the wake of January’s $530mln hack of Japanese crypto exchange Coincheck.

Despite the security lapse, Japan’s licensing system for exchanges has seen considerable popularity since an legal overhaul of the space in April 2017.

Licensed members will even form part of an umbrella self-regulatory group from April this year, with details still to be ironed out, Cointelegraph recently reported.

Meanwhile, technical errors on mainstream consumer interfaces are far from unheard of. In January, 2018 online retailer Overstock revealed a glitch that resulted in customers being able to choose between Bitcoin and Bitcoin Cash as payment options, with the price figure remaining the same.
