SBI's new exchange launch got postponed from January 30-th until today
"After the hacking attack on Japanese crypto exchange Coincheck in late January 2018, amid security concerns and subsequent changes in the business environment, the full launch of its cryptocurrency spot trading service "VCTRADE" -- which had been serving a small number of customers since 30 January 2018 -- got postponed.
Then, on 26 April 2018, president of SBI Holdings, Yoshitaka Kitao, announced that the service would be launched by Summer 2018. He promised that once SBI Virtual Currencies was fully open for trading, it would become "number one in the blink of an eye" and promised that VCTRADE would have the "industry's lowest spread.""
So, I guess we shouldn't be surprised that QUIONE got delays too.
