Victims of a crypto hack don't just suffer immediate financial loss. According to a new report from Immunefi, affected tokens plunge by an average of 61% in six months, and rarely rise again. A brutal observation which redraws the perception of risk in the crypto universe.
In brief
- Hacked tokens drop by an average of 61% in the six months following the attack.
- Nearly 84% never regain their initial price over this period.
- Crypto losses reach $4.67 billion across 191 recent hacks.
Immediate market sanction in the face of crypto hacks
Between 2021 and 2025, Immunefi, one of the leading bug bounty platforms in the crypto ecosystem, screened 425 security incidents. The observation is clear: the average cost of a hack has now reached $25 million. But the real shock is the market which absorbs it.
On average, affected tokens lose 61% of their value within six months following an attack. And nearly 84% of them never regain their pre-hack price. A hack therefore acts as an almost definitive sentence for the development of a project.
This phenomenon reflects a profound change in perception. As Immunefi CEO Mitchell Amador points out, the market has become “less forgiving.” A security breach no longer passes for a simple technical accident: it betrays structural fragilities, faulty governance, poorly audited code, insufficient risk management.
The repercussions go well beyond the initial loss:
- prolonged fall of the token;
- liquidity flight;
- loss of credibility with investors;
- developmental paralysis.
In a crypto market today dominated by institutional players with high demands, this erosion of trust often proves impossible to erase.
Systemic risk amplified by DeFi and the concentration of funds
The other major lesson from the report concerns the very structure of the market. Losses are not distributed evenly: they are concentrated in a limited number of massive incidents. Of the $4.67 billion lost in 2024 and 2025, just five attacks were enough to swallow up 62% of the total.
Centralized platforms embody this paradox. Less frequently targeted, they nevertheless accumulate considerable volumes of capital. Around twenty attacks generated more than half of the overall losses, proof that the size of a target matters as much as its frequency of exposure.
The most formidable danger, however, comes from DeFi. Its networked architecture functions as a crisis amplifier: an isolated incident can instantly propagate through loan, liquidity or collateral protocols that were not directly targeted.
The collapse of Elixir's USD stablecoin at the end of 2025 is the most striking illustration of this. Elixir had placed around 65% of its collateral with Stream Finance. When the latter revealed a loss of $93 million attributable to an external manager, the chain reaction was devastating.
Stream's xUSD stablecoin fell 77%, deUSD redemptions were immediately suspended, panic selling ravaged Curve pools, and deUSD ultimately lost more than 97% of its value.
A single failure in a partner protocol was enough to take everything away.
The crypto market is entering a new era, that of demand. A hack is no longer an unfortunate accident, it's a test of survival. A breach does not only destroy funds: it destroys trust, and with it, the very value of the project. Investors no longer forgive, they punish, often permanently.
