Crypto traders rely on chart patterns and probabilities to predict price movements, identify opportunities, and set up trades. However, despite using technical tools, on-chain analytics, and fundamental metrics, the crypto market is full of unexpected twists. 

No matter how thoroughly traders analyze likely scenarios, unpredictable events can derail the market. These unexpected occurrences, known as "crypto black swan" events, can lead to panic selling and disrupt even the best-prepared plans. 

A crypto black swan is any major event that dramatically impacts cryptocurrency prices, such as a blockchain hack or global economic shock. Even with the right tools, traders must stay prepared to respond calmly when such events arise. 

Notable Events  

Mt. Gox Hack (2014): 

The largest crypto exchange at the time, Mt. Gox, processed 70% of Bitcoin transactions. When hackers stole 750,000 BTC, the incident severely damaged Bitcoin’s reputation and led exchanges to adopt security measures like cold storage and KYC policies. 

Ethereum DAO Hack (2016): 

Ethereum’s DAO, an early experiment in decentralized governance, was hacked, resulting in the theft of 31 million ETH. To recover, Ethereum developers executed a hard fork, creating a new blockchain to refund affected users. 

China's Crypto Mining Ban (2021): 

China's ban on cryptocurrency mining and transactions caused Bitcoin to plunge from $60,000 to $30,000 and significantly reduced its hashrate. The market eventually adjusted, but the ban had a major short-term impact. 

TerraUSD Collapse (2021): 

Terraform Labs' TerraUSD (UST) stablecoin lost its peg to the U.S. dollar, causing $45 billion to drain from the market within days, sparking fear and regulatory scrutiny.
