Cryptocurrencies have been around for years, but much of this landscape remains uncharted territory—requiring cautious navigation. Countless individuals have fallen victim to elaborate scams, losing their life savings in the process.
According to Chainalysis’ Crypto Crime Report, **$14 billion worth of cryptocurrency was stolen in 2021 alone**, doubling the $7.8 billion lost in 2020.
Below, we dissect the 10 largest cryptocurrency scams in history, along with actionable tips to help you avoid them.
Why Are Crypto Scams So Dangerous?
Cryptocurrencies are irreversible: once a transaction is completed, no one—not miners, developers, or even Satoshi Nakamoto—can reverse it. This means victims cannot recover stolen funds.
Additionally, Bitcoin addresses use pseudonyms (30-character strings unrelated to real-world identities), making it nearly impossible to trace fraudsters.
Now, let’s examine the 10 most devastating scams.
