Recent events in the cryptocurrency landscape, including a notable breach at Binance resulting in an estimated $6.3 billion loss, highlight the increasing concerns about asset security within the digital financial sector.

This article explores the ten most significant reported thefts in the cryptocurrency realm, detailing their financial implications and how these incidents continue to shape the industry.

1. Binance: $6.3 Billion (Approx. ₹60,066 Crore)

On October 30, 2026, Binance reported a grave security breach impacting approximately $6.3 billion. An investigation suggested that the theft stemmed from a compromised laptop of a DevOps engineer, which permitted unauthorized withdrawals. The exchange reported that around $3 billion in affected assets were successfully frozen through collaboration with blockchain partners, and promised to cover the losses from its Secure Asset Fund for Users (SAFU) alongside company resources.

2. Bybit: $1.5 Billion (Approx. ₹14,301 Crore)

On February 21, 2025, Bybit experienced a substantial theft valued at around $1.5 billion, marking it as one of the largest thefts recorded at that time. The incident was attributed to North Korean cyber actors who shifted the stolen assets across numerous blockchain addresses.

3. Poly Network: $610 Million (Approx. ₹5,816 Crore)

In August 2021, the Poly Network decentralized finance platform was exploited, leading to the theft of approximately $610 million. Vulnerabilities in its transaction facilitation system were exposed. Interestingly, the attacker returned a majority of the stolen funds post-incident.

4. BNB Chain: $586 Million (Approx. ₹5,587 Crore)

October 2022 saw a breach of BNB Chain’s cross-chain bridge, with an attacker utilizing a system vulnerability to create or withdraw nearly two million BNB tokens valued at about $586 million. However, not all funds were lost, as validators acted to curtail the illicit movement.

5. Ronin Network: $540 Million (Approx. ₹5,148 Crore)

Hackers compromised the Ronin Network in March 2022, pilfering around $540 million, primarily from the popular blockchain game Axie Infinity. This attack has been linked to North Korea’s Lazarus Group, showcasing the intersection of gaming and cryptocurrency security.

6. Coincheck: $530 Million (Approx. ₹5,053 Crore)

In January 2018, Japan’s Coincheck faced a major security incident when NEM tokens amounting to approximately $530 million were stolen from a hot wallet connected to the internet. This event intensified scrutiny of the security protocols within cryptocurrency exchanges.

7. Mt. Gox: $500 Million (Approx. ₹4,767 Crore)

Between 2011 and 2014, Mt. Gox lost close to $500 million in Bitcoin, leading to its eventual collapse and bankruptcy in 2014. This incident remains one of the earliest significant security failures in the cryptocurrency industry.

8. FTX: $477 Million (Approx. ₹4,548 Crore)

In November 2022, FTX experienced a substantial drain of roughly $477 million in cryptocurrency from wallets associated with the exchange as it entered bankruptcy. The circumstances of the withdrawal raised questions about whether it was an external hack or internal mismanagement.

9. Bitget: $350 Million (Approx. ₹3,337 Crore)

In September 2026, Bitget reported a theft amounting to $350 million, underscoring the persistent security vulnerabilities faced by centralized exchanges. The finality of the unrecovered loss may still fluctuate based on ongoing assessments.

10. Wormhole: $320 Million (Approx. ₹3,051 Crore)

The Wormhole blockchain bridge was exploited in February 2022, resulting in the loss of approximately 120,000 wrapped Ether tokens valued at $320 million. The attacker took advantage of a verification mechanism flaw, although the stolen funds were later replaced by Jump Trading’s crypto unit.

Conclusion: The Broader Implications

These significant thefts reveal that the vulnerabilities in cryptocurrency security extend beyond just exchanges; they permeate mining pools, blockchain bridges, and decentralized finance platforms. The financial impact of these breaches is complex, changing based on whether stolen assets are subsequently recovered or frozen. Additionally, fluctuations in cryptocurrency values could further affect the total financial repercussions over time.
