Cryptocurrency Hacks: The Biggest of All Time

Cryptocurrency is a digital or virtual currency that uses cryptography to secure its transactions and control the creation of new units. Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control.

While cryptocurrencies offer a number of advantages over traditional currencies, they also come with their own set of risks. One of the biggest risks is cryptocurrency theft, also known as a hack. A hacker can gain access to your cryptocurrency holdings in a number of ways, including exploiting security vulnerabilities on exchanges and mining pools, stealing your login credentials, or even installing malware on your computer to steal your private keys.

1. Mt. Gox: lose 850,000 bitcoins 

Mt. Gox was a Japanese bitcoin exchange that lost 850,000 bitcoins in 2014. This caused a lot of chaos and inconvenience for customers who stored their bitcoins with Mt. Gox. 

The hack happened on February 7th, when an unknown hacker stole around 850,000 BTC (worth $450 million at the time) from the company’s hot wallet. It was the biggest cryptocurrency hack of all time and it still remains one of the most significant hacks in history. 
Mt. Gox rapidly became known as “the world’s largest bitcoin bubble machine” after this event because its users could no longer withdraw their bitcoins due to security concerns raised by this theft.

2. Bitfinex: 120,000 bitcoins stolen 

On 1 August 2017, Bitfinex was hacked and 120,000 bitcoins were stolen. This theft ranks as the 2nd largest cryptocurrency hack of all time.
Bitfinex is one of the most popular exchanges for buying and selling cryptocurrencies. 
The stolen bitcoins were then used to purchase other cryptocurrencies on various exchanges.

3. Bitconnect: investors fraudulently withdrew over 1 million dollars 

In December of 2017, Bitconnect was one of the biggest cryptocurrency hacks in history. The company’s investors lost over 1 million dollars due to fraud.

Bitconnect was a Ponzi scheme where early investors received high returns on their investments, but laterals and new investors were not able to earn as much money. As a result, many people lost their money when the scheme collapsed.

Cryptocurrency scams are on the rise, with losses estimated at over $2 billion this year alone. It is important for business owners to be aware of these schemes and take steps to protect themselves before it’s too late.


Even though cryptocurrency is a relatively new concept, it has already been subject to some major hacks. In 2014, Mt. Gox, one of the first and biggest cryptocurrency exchanges, lost 850,000 bitcoins in what was then the biggest hack of all time. More recently, in 2016, Bitfinex, another large exchange, had 120,000 bitcoins stolen. And just last year, Bitconnect was hit with an even bigger scandal when investors fraudulently withdrew over 1 million dollars from the platform. With so much money at stake, it’s no wonder that hackers are targeting cryptocurrency exchanges and wallets. As the industry grows and more people invest in cryptocurrencies, we can only expect that these types of incidents will become more common.
