Zaif, the Japanese cryptocurrency exchange, which last year lost over 60 million USD to hackers, resumed operations after a publicly listed Japanese investment firm Fisco took over the crypto business, paying 5 billion Japanese yen or roughly 44,7 million USD. Zaif Crypto Exchange was hacked back in September 2018 and lost nearly 7 billion Japanese Yen or 62,5 million USD worth of Bitcoins, Monacoins and Bitcoin Cash. Since the hacker attack registration of new members has been suspended, while trading, depositing and withdrawing of Monacoins has been frozen since October 10th 2018.
The listed-acquirer Fisco has a market-cap of around US$70-80mn...another hack and the whole group will be wiped out
