Crypto Sector Loses $2.2 Billion in First Half of 2025 Due to Hacks and Fraud

The cryptocurrency sector faced significant challenges in the first half of 2025, with massive losses reported across various digital assets. The sector suffered significant losses amounting to over $2.2 billion due to hacks, fraud, and security breaches. Between January and June, 344 blockchain incidents were reported, with the majority of losses stemming from just 34 wallet hacks. The increasing complexity and violence associated with attacks on the cryptocurrency sector underline the urgent need for stronger security measures. Weak private key management has been identified as one of the most critical vulnerabilities. Frequently, keys are stored in insecure environments, not encrypted, or controlled by a single entity, making them easy targets for hackers. This single point of failure continues to represent one of the industry’s most significant risks, leading to multi-billion dollar losses.

CertiK’s data reveals that $1.7 billion of the stolen funds were due to breaches of wallet security. Additionally, $410 million was lost to 132 different phishing scams. February witnessed the year’s largest single incident, where a security vulnerability resulted in a $1.5 billion loss from Bybit’s staked ETH wallets. In May, the Cetus Protocol fell victim to a massive hack exploiting a smart contract flaw, resulting in $225 million in losses. Sui validators managed to recover $162 million from this incident. Notably, losses from smart contract vulnerabilities alone soared to $229 million in May, a stark increase from the $5 million recorded the previous month.

The report also highlighted a worrying increase in physical attacks. The first half of the year recorded 32 incidents involving violence, kidnapping, and ransom attempts. Efforts from white hat hackers, in collaboration with law enforcement and exchanges, have resulted in the recovery of approximately $187 million. The cryptocurrency sector faced significant challenges in the first half of 2025, with massive losses reported across various digital assets. Bitcoin, the leading cryptocurrency, managed to stay relatively stable, carrying the market through a volatile period. However, other major cryptocurrencies such as Ethereum's ETH and Solana's SOL, along with smaller-cap coins, experienced steep declines. This disparity led to a notable increase in Bitcoin's market share, which climbed by nine percentage points to 64%, the highest level since January 2021.

The first half of the year was marked by a series of high-profile hacks, with nearly $2.1 billion stolen across 75 incidents. This figure surpassed the $1.8 billion lost in the previous year, highlighting the growing threat of cybersecurity breaches in the cryptocurrency sector. The majority of these losses, over 80%, were attributed to vulnerabilities in infrastructure, underscoring the need for enhanced security measures. Despite the overall market downturn, Bitcoin's performance stood out. The cryptocurrency reached record highs just below $112,000, driven by optimism surrounding the Trump administration's crypto-friendly policies. The appointment of Paul Atkins as SEC chair and the introduction of a dedicated crypto czar further bolstered market sentiment. However, a sharp sell-off in April, following Trump's "Liberation Day" tariffs, briefly cooled investor enthusiasm. By the end of June, as stocks reached record levels, crypto reasserted itself as a top-performing asset, with Bitcoin up 14% year to date, outperforming the S&P 500's 5% gain.

The crypto industry's triumphant first half was also marked by the rise of trading platforms. Coinbase, a leading crypto trading platform, soared more than 40% year to date, while Robinhood rallied more than 130%. These platforms have emerged as key players in the crypto space, with Coinbase dominating US trading and serving as a custodian for the majority of US spot bitcoin ETFs. Circle, an issuer of stablecoins USDC, also saw its shares surge as much as 500% above their recent IPO price, fueled by regulatory developments. The first half of 2025 saw a significant split in the cryptocurrency market, with Bitcoin's dominance growing at the expense of altcoins. The so-called "challengers" to Bitcoin, including Ethereum and Solana, experienced a significant decline, losing over $300 billion in market value. This trend highlighted the volatility and risk associated with investing in smaller-cap cryptocurrencies, as well as the resilience of Bitcoin in the face of market turbulence.

The cryptocurrency sector's performance in the first half of 2025 was characterized by a mix of challenges and opportunities. While Bitcoin's stability and record highs provided a glimmer of hope, the steep losses experienced by other cryptocurrencies and the increasing threat of cybersecurity breaches underscored the need for caution and enhanced security measures. As the market continues to evolve, investors and industry participants will need to navigate these challenges to capitalize on the opportunities presented by the cryptocurrency sector.
