Still, a small portion, representing millions in value, was sold or withdrawn before the controls took effect.<\/p>\n<h2 class=\"wp-block-heading\">FSS investigation and regulatory response<\/h2>\n<p>Initially launching an emergency review, the FSS escalated its examination to a full-scale formal investigation. Bithumb was notified of the probe signalling a deep dive into what went wrong and whether internal controls violated the Virtual Asset User Protection Act or other regulatory standards.<\/p>\n<p>FSS Governor Lee Chan-jin has emphasized that the episode revealed systemic weaknesses in internal control and electronic ledger systems at the exchange. Regulators are examining how an exchange with far fewer actual reserves was able to record and disburse phantom Bitcoin balances so rapidly.<\/p>\n<p>Depending on what investigators find, the probe could lead to sanctions against Bithumb, including fines or even suspension of operations if negligence or legal violations are confirmed. The FSS has also noted that users who sold erroneously credited Bitcoin may be legally obligated to return it as unjust enrichment under current interpretations of Korean law.<\/p>\n<p>    <!-- .cn-block-related-link --><\/p><\/div>\n<p><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>South Korea\u2019s Financial Supervisory Service (FSS) has escalated scrutiny of major cryptocurrency exchange Bithumb following an unprecedented operational mistake in which the firm accidentally credited customers with tens of billions&hellip;<\/p>\n","protected":false},"author":1,"featured_media":21681,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-21680","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cryptocurrency"],"_links":{"self":[{"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/posts\/21680","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/comments?post=21680"}],"version-history":[{"count":1,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/posts\/21680\/revisions"}],"predecessor-version":[{"id":21682,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/posts\/21680\/revisions\/21682"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/media\/21681"}],"wp:attachment":[{"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/media?parent=21680"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/categories?post=21680"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/bitunikey.com\/news\/wp-json\/wp\/v2\/tags?post=21680"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
