How to protect your cryptocurrencies from market downturns

Throughout its short but intense history, we have witnessed brutal crashes that have wiped out billions of dollars in capitalization and left millions of investors with significant losses. However, each crisis offers valuable lessons that, while they do not guarantee immunity from future crashes, do allow for building stronger strategies to protect wealth.

The 2018 crash and the false diversification

After the historic rally at the end of 2017 that took Bitcoin up to $20,000, the market entered into a downward spiral throughout 2018. Bitcoin fell to $3,000, losing more than 80% of its value, while many altcoins practically disappeared.

The decline was not caused by a specific event, but by a combination of factors: the end of the speculative cycle, the ban on crypto advertising by Google and Facebook, and growing regulatory pressure.

The most important lesson from 2018 is that diversification within the crypto universe does not offer real protection during broad-based crashes. Virtually all digital assets fell in parallel, following Bitcoin’s trend.

Investors who thought they were diversified by holding ten different altcoins discovered that, in reality, all their assets were correlated. True diversification means having exposure to non-correlated asset classes outside the crypto ecosystem.

New risks: the case of crypto casinos

The growth of the blockchain ecosystem has given rise to new applications that go beyond simple exchange and value storage. A notable example is the proliferation of gaming platforms that operate exclusively with cryptocurrencies.

These crypto casinos perfectly illustrate several risks faced by investors. First, the volatility of the asset being wagered: winning at a crypto casino during a bear market may mean ending up with less real value than you started with.

In addition, many of these platforms operate without clear regulation, which increases the risk of fraud or sudden disappearance. Custody risk remains present as well: depositing funds in a crypto casino means trusting the platform to keep those assets safe and available. This reality reminds us that the crypto ecosystem, though innovative, is riddled with services where trust can break down quickly.

Terra/LUNA: when mathematics aren’t enough

In May 2022, the Terra ecosystem collapsed within days, wiping out over $40 billion in value. UST, its algorithmic stablecoin supposedly pegged to the dollar, lost its peg and triggered a death spiral that dragged LUNA, the protocol’s native token, from over $80 to practically zero.

UST’s model relied on a theoretical arbitrage mechanism that proved insufficient in the face of a massive crisis of confidence. Moreover, the Anchor protocol offered 20% annual returns on UST deposits, an unsustainable promise that attracted capital but also created a single point of systemic failure.

The lesson from Terra is twofold: first, not all stablecoins offer the same security; stablecoins backed by real assets like USDC or USDT are structurally more robust than algorithmic ones.

Second, any promise of extraordinary guaranteed returns should be viewed with extreme caution. In finance, there are no free lunches, and abnormally high returns usually hide extraordinary risks.

FTX: the betrayal nobody expected

Barely six months after the Terra disaster, the crypto world suffered another devastating blow: the collapse of FTX, one of the largest and seemingly most reliable exchanges in the sector.

In November 2022, a journalistic investigation revealed that Alameda Research, FTX’s sister quantitative fund, had more than $14 billion in FTT tokens, the exchange’s native asset, on its balance sheet.

This revelation uncovered a web of mismanagement, conflicts of interest, and, according to subsequent allegations, outright fraud. Sam Bankman-Fried, founder of FTX and a prominent figure in the sector, had used customer funds to cover Alameda Research’s losses. When clients rushed to withdraw their funds, FTX could not meet the demand and declared bankruptcy.

Investors lost billions, and Bankman-Fried himself was sentenced in 2024 to 25 years in prison on multiple counts of fraud.

The FTX case offers multiple critical lessons: the counterparty risk of depositing cryptocurrencies on an exchange, the importance of corporate governance (FTX had only two members on its board of directors and kept chaotic accounting records), the illusion of institutional backing (it had raised hundreds of millions from prestigious venture capital funds), and above all, the ongoing relevance of the mantra “not your keys, not your coins.” Keeping cryptocurrencies on exchanges for long periods exposes you to unnecessary risks.

Practical strategies to protect your assets

Learning from these historical lessons, investors can implement concrete strategies to better protect their wealth. Real diversification is essential: including traditional assets such as stocks, bonds, and real estate in your portfolio reduces exposure to crypto risk.

A portfolio that is 100% crypto is completely exposed to the sector’s violent cycles. Long-term self-custody, using hardware wallets to store cryptocurrencies that are not intended for active trading, eliminates counterparty risk associated with exchanges. This requires responsibility in handling private keys, but it is the only real way to own cryptocurrencies.

Skepticism toward extraordinary promises is essential: guaranteed 20% annual returns, tokens that “can only go up,” or platforms that seem too good to be true often hide structural problems or outright frauds.

Setting limits and rebalancing periodically helps prevent exposure from growing uncontrollably during rallies and maintains discipline during downturns.

Equally important is having a pre-determined action plan for bear markets, which avoids emotional decisions during crises.

Finally, ongoing education is critical: truly understanding the projects you invest in, following reliable information sources, and maintaining a critical mindset are essential in an ecosystem where innovation coexists with fraud.

Conclusion

Cryptocurrency market crashes are not occasional anomalies but recurring features of a young, speculative, and constantly evolving sector.

The 2018 crash taught that correlation between crypto assets is very high during crises. Terra/LUNA showed that even apparently sophisticated mechanisms can collapse if their fundamentals are weak.

FTX reminded us that blind trust in centralized platforms, no matter how prestigious they seem, is dangerous. Protecting assets in this environment requires a multidimensional approach: real diversification beyond crypto, self-custody when possible, skepticism toward extraordinary promises, emotional discipline, and constant education.

There is no strategy that completely eliminates risk, but understanding past lessons allows you to build stronger defenses against future crashes.
