2025 Becomes One of Crypto’s Worst Years After Massive Losses

The post 2025 Becomes One of Crypto’s Worst Years After Massive Losses appeared first on Coinpedia Fintech News

Crypto’s 2025 will be remembered as a year when confidence slowly collapsed under the weight of hacks, scams, and insider abuse. What began with hype, political tokens, and renewed optimism quickly turned into a long stretch of security failures that exposed deep structural weaknesses across the industry. By year’s end, total losses had crossed $3.5 billion, making 2025 one of the most damaging years in crypto history.

The Bybit Hack Became the Defining Moment

The biggest shock came in February with the $1.5 billion Bybit hack, now widely seen as the largest DeFi breach ever recorded. Unlike older attacks that targeted smart contract bugs, this incident exploited the supply chain. Hackers compromised Safe wallet’s signing interface, turning trusted infrastructure into an attack vector. CertiK later confirmed that supply-chain attacks were the most destructive threat of the year, responsible for $1.45 billion in losses across just two incidents, with Bybit accounting for nearly all of it.

Bybit moved quickly, guaranteeing full asset backing and launching a large bounty program to trace stolen funds. While much of the stolen crypto was eventually tracked, the incident permanently shifted how exchanges think about security.

AI Scams Target People Not Code

As major platform hacks made headlines, a quieter threat grew even faster. AI-powered phishing and social engineering attacks surged throughout the year. Hackers used voice cloning, fake support calls, and impersonation scams to trick users and insiders. One of the most damaging examples involved Coinbase support staff, where attackers gained privileged access using AI tools, leading to hundreds of millions in losses.

Pig butchering scams also escalated. These long-term romance scams drained victims through emotional manipulation, costing billions globally. In one case, an investor lost an entire Bitcoin retirement fund. U.S. authorities later seized over $225 million tied to these scams, highlighting how widespread the damage had become.

Users Bear More Risk Than Ever

Data showed that individual wallets made up a much larger share of losses compared to earlier years. While major breaches were fewer, they were far more severe. Weak key management, phishing links, and fake wallet updates drained thousands of users, proving that everyday investors carried growing risk.

A Year That Never Recovered

The warning signs were there early. January saw Trump-linked tokens collapse after insider selling, fake political launchpads drain retail, China tighten OTC restrictions, and Phemex lose over $69 million. February followed with the LIBRA collapse, deepfake scams, the Cetus exploit, and Bybit’s historic breach.

Spring and summer only made things worse. Solana was flooded with rug pulls, fake audits, and AI-generated whitepapers. GMX V1, Nobitex, and several bridges were exploited, while smaller Layer 1 chains faced validator failures and permanent stablecoin depegs. By June, hack losses had already crossed $2 billion.

Trust Breaks by Year-End

The final quarter sealed the damage. October’s Binance anomaly caused extreme price dislocations and liquidation cascades, dragging Bitcoin down from $122,000 to near $104,000. November and December brought institutional wash trading revelations, fresh outages, and a $1 trillion wipeout in total market value. 

By the end of 2025, trust across crypto was deeply shaken. The year exposed an industry struggling not just with security flaws, but with governance, transparency, and the human cost of unchecked innovation. At present Bitcoin trades at $87,711.
