What happened
On March 29, 2019, Bithumb detected abnormal withdrawals from company hot wallets. More than 3 million EOS and 20 million XRP, reported at roughly $19 million, were transferred out. Bithumb said the assets were its own and suspected insider involvement because it had not identified an external intrusion route; the allegation was an assessment, not a confirmed attribution.
