Investors were able to purchase Bitcoin for free on the Japanese cryptocurrency exchange last week, reports Reuters, after a system glitch saw 20-minutes of free coins.
Zaif, the exchange run by Tech Bureau Corp, has revealed that seven traders were able to buy Bitcoin without handing over any yen in return, during a short window that was thankfully brief enough to disallow any illegitimate profit.
One opportunistic investor reportedly tried to order 2,200 trillion yen worth of Bitcoin before selling it. Zaif voided the trades after discovering the error.
This incident puts cryptocurrency in the spotlight again after $530 million of digital money was stolen from Coincheck last month. The 16 exhanges currently registered with the Japanese government will form a self-regulatory body from April.
