Newcomers are often targeted because crypto transactions are irreversible. Once tokens leave your wallet, there is no customer support line to call. Some of the most frequent scams include:
● Phishing attacks: Fake websites, emails, or wallet pop-ups designed to trick you into revealing your private key or seed phrase.
● Pump-and-dump schemes: Groups coordinate to rapidly buy a low-liquidity token, advertise it on social media, and sell once unsuspecting buyers enter.
● Fake airdrops and giveaways: Scammers promise “free tokens” but require you to click malicious links or send small amounts of crypto first.
Even experienced investors can be caught off guard. Phishing, in particular, has become increasingly sophisticated, with attackers cloning exchange websites or exploiting Google ads to appear credible.
Crypto protocols are governed by code. If there’s a bug in that code, funds can be stolen. Hacks exploiting smart contracts have drained billions from decentralized finance (DeFi) applications.
While some projects undergo security audits, an audit is not a guarantee of safety. Attackers often discover novel ways to exploit contracts even after review. Flash-loan attacks, where hackers borrow massive sums and manipulate protocols within a single transaction, are a common method of exploitation.
Investors using DeFi should understand that interacting with a smart contract carries inherent risk, even if the platform is well-known.
Before putting money into a new token or protocol, a basic due diligence process can help identify risks. Here are the key things to review:
● The team: Are the developers public and credible, or anonymous with no track record?
● Token distribution: Are tokens heavily concentrated among insiders? If a handful of wallets control most of the supply, they can crash the price at any time.
● Liquidity: Is the token listed on reputable exchanges with real trading volume, or only thinly traded on smaller, obscure platforms?
Projects that lack transparency, promise “guaranteed returns,” or advertise yields that seem too good to be true often are exactly that.
Not all losses in crypto come from malicious actors. Some come from systemic failures.
● Stablecoin depegging: Stablecoins are meant to track the value of assets like the U.S. dollar. But algorithmic stablecoins like TerraUSD collapsed in 2022, wiping out tens of billions of dollars when they lost their peg.
● Exchange insolvency: Centralized platforms such as FTX and Celsius failed due to mismanagement and misuse of customer funds.
These events highlight the importance of custody decisions. Keeping large balances on unregulated exchanges introduces risks that are beyond an investor’s control.
Beyond scams and hacks, volatility itself is a form of risk. Sudden price swings can trigger forced liquidations for leveraged traders or panic selling among retail investors. Risk management techniques, like using limit orders, avoiding leverage, and diversifying holdings, are essential to surviving crypto’s natural volatility.
While risks cannot be eliminated, they can be managed. Practical steps include:
● Use reputable exchanges and wallets.
● Double-check URLs and never share your recovery phrase.
● Diversify across assets and avoid concentrating in speculative tokens.
● Start with small test transactions when using a new protocol.
Above all, invest with a healthy skepticism. In crypto, if something sounds too good to be true, it usually is.
Crypto’s risks are real and unavoidable. Scams, hacks, systemic failures, and volatility have cost investors billions. But with awareness, discipline, and a cautious approach, many of these risks can be mitigated. The most successful investors are not the ones who chase every opportunity, but those who protect their capital while selectively participating in credible projects.
In the final chapter, we’ll bring these lessons together and look at how to build a crypto portfolio, including lessons on allocation strategies and long-term discipline.
