The Human Factor Is Now the Primary Risk in Crypto
For years, security in crypto was framed as a technological arms race. Stronger blockchains, better cryptography, more resilient infrastructure. That battle has largely been won. Yet financial losses continue to rise—not because systems fail, but because people do.
The most effective attacks in crypto today no longer target code. They target cognition.
According to Ali Sina Mohaghegh, a Dutch entrepreneur and blockchain analyst, fraud has evolved from a technical challenge into a behavioral one. As blockchains have matured, scammers have abandoned brute-force methods in favor of something far more efficient: psychological manipulation.
“Nothing breaks on-chain,” Mohaghegh notes. “What breaks is the decision-making process before a transaction is signed.”
When Security Becomes a Matter of Psychology
Modern crypto fraud relies on subtle pressure, borrowed credibility, and carefully constructed narratives. Instead of exploiting vulnerabilities in software, attackers exploit patterns in human behavior—authority bias, urgency, and the instinct to resolve perceived threats quickly.
Mohaghegh’s work sits at the intersection of economics, forensic blockchain analysis, and behavioral risk. With an academic background in fiscal economics and advanced training in on-chain research, he examines not just where funds move, but why victims act the way they do.
Alongside his research, he is a co-owner of crypto exchange Bitdenex and advises international companies on transaction risk and fraud prevention. In that capacity, he observes the same reality repeatedly: large-scale losses almost always stem from user-initiated actions that cannot be reversed.

Two Incidents That Capture a Broader Trend
Recent high-profile cases, independently documented by leading on-chain investigators, illustrate how little technical sophistication is now required to cause massive damage.
In one case, victims were approached by individuals posing as customer-support representatives of a major exchange. Communication was polished, calm, and convincing. The attackers didn’t rush their targets—they guided them.
By framing routine actions as “security procedures,” victims were led to approve transactions themselves. From a blockchain perspective, every step was legitimate. From a human perspective, it was carefully orchestrated deception.
Once access was obtained, stolen assets were dispersed across wallets and later spent conspicuously—on digital assets tied to social status, nightlife, and high-risk online activities. Ironically, that visibility later helped investigators reconstruct the flow of funds.
A second incident demonstrated even more starkly how devastating a single moment of misplaced trust can be. One investor lost hundreds of bitcoin in a single transfer after being contacted by attackers impersonating both an exchange and a hardware-wallet provider.
There was no malware. No exploit. No system failure.
Just one irreversible transaction, executed exactly as designed.
Why Experience Doesn’t Protect You
A persistent myth in crypto is that fraud primarily affects newcomers. Data and case studies increasingly suggest the opposite.
High-net-worth and experienced investors are often more exposed, not less. They move quickly, manage complex systems, and are accustomed to acting decisively under uncertainty. That efficiency, when paired with credible-looking authority, can become a liability.
Mohaghegh points to several recurring factors:
- Familiarity with risk reduces hesitation
- Professional language lowers suspicion
- Controlled urgency suppresses second opinions
- Technical complexity distracts from core questions
- Reputational concerns delay disclosure
The result is a class of victims who know the technology well, yet are vulnerable precisely because the attack bypasses it.
The Illusion of Legitimacy
What makes social-engineering fraud particularly dangerous is its after-the-fact appearance of legitimacy. Transactions check out. Wallets behave as expected. There is no obvious point of failure to reverse or patch.
“The blockchain is indifferent,” Mohaghegh explains. “It records outcomes, not intent.”
That indifference is both its strength and its weakness.
The Only Sustainable Defense
There is no software update that can fully eliminate social engineering. The most effective countermeasures are procedural and behavioral.
Simple rules, consistently applied, remain the strongest defense:
- Legitimate support teams never request credentials or recovery data
- Unsolicited contact should default to distrust
- Every signature is final, regardless of context
- Verification must override urgency
Skepticism, in this environment, is not cynicism—it is operational discipline.
Security in Crypto Is Now a Human Skill

Through his firm Netzach & Co, Mohaghegh focuses on education, forensic clarity, and decision-making frameworks. The goal is not fear, but fluency: understanding how scams are structured, which signals recur, and how manipulation presents itself when wrapped in professionalism.
As crypto matures, the limiting factor in security is no longer encryption strength or network resilience. It is judgment under pressure.
In a system built on irreversible actions, the ability to pause, verify, and question may be the most valuable asset of all.
