No this is not the first that a cryptocurrency exchange website was hacked into. Throughout the years, there have been numerous renowned data breaks. Among the most notable examples are:

Mt. Gox: The biggest cryptocurrency exchange then, Mt.Gox experienced a breach in 2014, causing the loss of around 850,000 bitcoin. One of the biggest ever bitcoin heists.

Bitfinex: That same year in 2016, the cryptocurrency exchange Bitfinex was hacked and more than 120,000 Bitcoin were stolen. At the time, this was the second biggest crypto hack.

Coincheck: Just the year prior, in 2018, Japanese crypto exchange Coincheck suffered from a massive $534 million NEM breach. Up until now this was only the third biggest crypto hack.

With all the high profile hacks that occurred, there have been several crypto exchanges who were able to bounce back. One example is Binance. And in 2019, the cryptocurrency exchange Binance has been hacked and over 7,000 bitcoins were stolen. But, the marketplace refunded the lost amounts to its customers, and its trade continued as usual.

Among them, Binance’s recovery from the hack comes as a result of various factors. The exchange first identified and contained the breach right away. Two, binance was financially strong enough to cover the losses and even pay back users. Thirdly, Binance kept communication open and transparent with its user base throughout the fiasco.


The CoinEx hack serves as a reminder that even those who you would assume are the most secure and seasoned in the world of Cryptocurrency exchange are not immune to attacks. However, it’s also a memory of how exchanges can survive this attack and keep on working. 

CoinEx’s return to normal prompts reflection on key factors in choosing a crypto exchange. This incident highlights the importance of both technical expertise and the team’s integrity in protecting user interests.
