BlockBeats News, April 6th, according to Yonhap News, the Financial Services Commission (FSC) of South Korea has requested local crypto CEXs to establish a system to reconcile internal books with actual crypto asset holdings every 5 minutes by the end of May and to disclose asset matching balances daily and undergo monthly external audits by accounting firms. This move is seen as a regulatory tightening measure following the incident in February this year where Bithumb mistakenly distributed 620,000 BTC to users.
