Bithumbの入力ミスで62万BTCを誤付与、13億ウォンが未回収

The statement's central claims—that the cryptocurrency exchange Bithumb experienced a system error and mistakenly issued a massive amount of Bitcoin—are overwhelmingly supported by the provided high-authority sources. Multiple reports from major news outlets like the Korea Economic Daily and Chosun Ilbo, as well as Bithumb's own official apology, confirm that a system or configuration error led to the incorrect distribution. Several sources, including the Korea Economic Daily and Chosun Ilbo, explicitly state the figure of 620,000 BTC being erroneously issued. The scale of the error, valued at over $40 billion, is also consistently reported by international sources like the BBC and Yahoo Finance.The only part of the statement that is not directly substantiated by the provided evidence is the specific figure of "13 billion Korean Won (₩) being unreturned." While a Yahoo Finance article suggests that some users managed to sell their erroneous Bitcoin, which would explain unreturned funds, no source confirms the 13 billion KRW amount. Furthermore, Bithumb's official statement claims that 99% of the incorrectly paid amount has been addressed, which implies some funds are outstanding but does not specify the value. Because the core event, its cause, and the massive scale (620,000 BTC) are all well-documented and confirmed, the statement is largely accurate. The unverified detail about the specific amount of unreturned funds prevents a definitive 'true' assessment, but the statement as a whole is very likely true in its substance.
