What has been stolen?

Though nothing official as to how the theft occurred has been announced, the most likely outcome is an online hack. As users assets are stored in online wallets, this makes them vulnerable to potential attacks by online hackers. It comes as a strong reminder to hold cryptocurrency in offline cold storage wherever possible.

Bithumb accounts for around 10% of all cryptocurrency trading volume and is one of Korea’s largest cryptocurrency exchanges.

The impact on the cryptocurrency markets as a whole is not yet clear, but the markets so far have remained relatively stable.

Hacks in the past such as the famous Mt.Gox hack has serious and long lasting effects on the cryptocurrency market because they handled over 70% of all trading at the time.

The exchange recently listed Cardano (ADA), but it’s unclear whether the thieves have targeted ADA.
