The Bithumb incident may affect CEX's business qualifications, and South Korean regulators will conduct an industry investigation into the situation of "Ghost Bitcoin" BlockBeats news, on February 9th, according to newspim, the President of the Financial Supervisory Agency of South Korea, Lee Can jin, expressed concern about the Bithumb erroneous transfer incident, calling it a "disaster" and mentioning the need to conduct a large-scale investigation and formulate countermeasures for the so-called "book transactions" of virtual assets that are not actually held. In particular, it is pointed out that if it is confirmed that Bithumb has committed illegal negligence, all possible measures under current laws will be taken, and it is mentioned that if the Digital Asset Basic Law, which is currently preparing for legislation, is passed, it may even implement sanction level regulation involving licensing rights, which means that the business of the virtual asset trading platform itself may be threatened. Li Canzhen stated at the "2026 Major Business Plan Briefing" held at the headquarters of the Seoul Financial Supervisory Authority that "after receiving the report of Bithumb's erroneous transfer incident, on-site inspections have been carried out. If it is confirmed that there is suspicion of illegal activities, the plan is to turn it into a formal investigation. This is a serious situation that undermines the reputation of the virtual asset trading platform itself. '' Li Canzhen emphasized that the biggest problem with this incident is that Bithumb traded 'virtual' currencies that it did not hold, which is an event that shakes the reputation of the entire virtual asset trading platform. We are also learning about the current situation of other trading platforms. This is the part that must be improved. '' Bithumb holds only 175 bitcoins as of September last year, with 42619 entrusted by clients, totaling only 42794 bitcoins. Considering that as many as 620000 bitcoins were mistakenly transferred, which is more than 14 times its holdings, this means that the equivalent of 580000 "ghost" bitcoins were issued. The reason why this situation is possible is that Bitcoin transactions are not actually conducted on the blockchain, but first only change the numbers on the internal ledger of the trading platform, known as the "book transaction" structure. This structure aims to achieve fast transactions and save transaction fees, and book transactions themselves are not illegal. The problem is that Bithumb has not established a security mechanism to prevent the payment of non-existent virtual assets.
