The cryptocurrency market has grown exponentially over the past decade, drawing millions of investors seeking innovation, decentralization, and potential high returns. However, with great opportunity comes significant risk. While the industry's security infrastructure continues to mature, cyberattacks remain a persistent threat.
In September 2020, hackers stole over $281 million from Kucoin, one of the world’s largest crypto exchanges. In August 2021, attackers drained more than $610 million from Poly Network—a blockchain interoperability platform. Then in 2022, $100 million vanished from Horizon Bridge, a cross-chain transfer protocol. These incidents highlight the vulnerabilities that still exist across platforms.
Beyond large-scale breaches, smaller but equally damaging scams like phishing emails and social media fraud are rampant. Fortunately, you can take proactive steps to protect your digital assets. This guide explores the safety of Bitcoin and other cryptocurrencies, how cybercriminals operate, and proven strategies to securely buy and store your investments.
Understanding Cryptocurrency Security Risks
Bitcoin and other digital currencies are traded online, which inherently exposes them to cybersecurity threats—similar to any internet-based financial activity. While blockchain technology itself is highly secure due to cryptographic verification and decentralized consensus, the points of interaction (exchanges, wallets, and user behavior) are where most risks emerge.
Cryptocurrencies are known for their high volatility, often experiencing sharp price swings within hours. This makes them more susceptible to market manipulation compared to traditional securities. Unlike stocks or bonds, crypto holdings aren’t protected by the Federal Deposit Insurance Corporation (FDIC) or the Securities Investor Protection Corporation (SIPC). If your funds are lost due to theft or human error, there’s no insurance backup.
Regulatory uncertainty also adds another layer of risk. Governments worldwide are still shaping policies around digital assets, which could impact accessibility, taxation, and legality in the future.

Despite these challenges, many investors find value in crypto when they apply disciplined security practices. Let’s examine how cybercriminals typically gain access to funds—and what you can do about it.
How Do Cybercriminals Steal Crypto?
Understanding the tactics used by hackers is key to defending against them. Common methods include:
- Exchange Hacks: Centralized exchanges hold vast amounts of crypto, making them prime targets. Platforms with weak security protocols have been compromised in the past, resulting in massive losses.
- Phishing Scams: Fraudsters send fake emails or direct messages that mimic legitimate services (like Coinbase or Binance). These often contain links to counterfeit login pages designed to steal your credentials.
- SIM Swapping: Attackers trick mobile carriers into transferring your phone number to a new SIM card. Once they control your number, they can bypass two-factor authentication (2FA) and reset passwords on crypto accounts.
- Rug Pulls (Pump-and-Dump Schemes): Developers promote obscure tokens with false promises, inflate prices through coordinated buying, then sell off their holdings—crashing the market and leaving investors with worthless coins.
These schemes don’t require breaking encryption—they exploit human psychology and system weaknesses. That’s why awareness and prevention are your best defenses.
4 Proven Strategies to Secure Your Crypto Investments
1. Choose the Right Storage Method
You have two main options: custodial storage (managed by a third party) or self-custody (you control the keys).
Option A: Use a Trusted Custodian
For beginners or those prioritizing convenience, storing crypto with a reputable custodian—such as a well-established trading platform—can be safer. Benefits include:
- Recovery support: If you forget your password, customer service may help you regain access.
- Simplified security: Reputable platforms implement advanced safeguards like cold storage, multi-signature authentication, and regular audits.
- Reduced complexity: Managing one login is easier than handling private keys and recovery phrases.
While some custodians restrict transfers between wallets, this limitation may not matter if your goal is long-term investment rather than active trading.
Option B: Self-Custody With Digital or Hardware Wallets
If you prefer full control, transfer your assets to a digital wallet (hot wallet) or a hardware wallet (cold wallet). Cold wallets—physical devices like USB sticks—are especially secure because they’re offline and immune to remote hacking.
However, self-custody comes with responsibility:
- Lose your private key or recovery phrase? Access is gone forever.
- Send crypto to the wrong address? Transactions are irreversible.
- Store your device improperly? It could be stolen or damaged.
Only opt for self-custody if you’re committed to learning best practices and maintaining strict digital hygiene.

2. Research Project Founders and History
Not all cryptocurrencies are created equal. Because launching a token requires minimal technical barriers, scams like rug pulls are common. The infamous OneCoin scheme, led by Ruja Ignatova, defrauded investors of over $4 billion before vanishing.
Before investing:
- Investigate the team behind the project. Are they transparent? Do they have verifiable experience?
- Look for public audits, whitepapers, and community engagement.
- Favor projects with institutional backing or long track records through market cycles.
Newer coins may offer high rewards—but they also carry higher risks. Due diligence reduces your chances of falling for deceptive schemes.
3. Only Use Reputable Crypto Exchanges
Your choice of exchange significantly impacts security. Avoid platforms promising unrealistic returns—high yields often signal unsustainable models.
Consider the case of QuadrigaCX: when its CEO died unexpectedly, users lost access to $190 million in assets because only he knew the password to the cold wallets. Similarly, Voyager Digital collapsed in 2022 after advertising yields up to 12%.
Choose exchanges that:
- Have strong funding and large teams.
- Publish proof-of-reserves and undergo third-party audits.
- Offer robust customer support and clear terms of service.
Sticking with established platforms minimizes exposure to operational failures and fraud.
4. Follow Essential Cybersecurity Best Practices
Adopting smart habits dramatically improves your safety:
- Never share private keys—treat them like passwords or cash.
- Avoid discussing your holdings online—this prevents targeting by SIM swappers.
- Verify email sources—check sender domains carefully before clicking links.
- Avoid social media DMs from unknown accounts—scammers often impersonate support staff.
- Enable two-factor authentication (2FA)—use authenticator apps instead of SMS when possible.
- Double-check wallet addresses before sending funds—mistakes are irreversible.
- Run a “penny test”—send a tiny amount first to confirm everything works before transferring larger sums.
- Reject unsolicited transactions or NFTs—they may contain malicious smart contracts.
These steps form a strong defense against common attack vectors.
