Bithumb Wins First Suit, User Must Return $145K in Mistaken BTC

The outcome matters for both exchanges and users, as it clarifies that mistaken digital asset transfers are not windfalls under South Korean law. With three similar lawsuits pending, the key question is whether courts consistently apply this principle, which could shape how exchanges handle error recovery and how users respond to such claims.
