Enhancing Crypto Security: 7 Effective Strategies to Prevent Hacks and Scams

Key Points:

Over $2.4 billion was stolen in the first half of 2025, exceeding the total for all of 2024.
Common traps like phishing and fake support are more damaging than sophisticated exploits.
Steps such as using strong 2FA, careful signing, separating hot and cold wallets, and preparation can significantly lower risks.

Cryptocurrency thefts continue to escalate, with over $2.4 billion reported stolen in the first half of 2025, surpassing the entire total of 2024. A standout incident involved the Bybit theft attributed to North Korean groups, which contributed to the rising statistics. However, the vast majority of losses stem from simple phishing links and scams.

Fortunately, enhancing your security doesn’t require expert knowledge. Here are seven critical habits to adopt in 2025:

1. Avoid SMS: Use Stronger 2FA Everywhere

If you still rely on SMS for your account security, you’re vulnerable.

2. Be Wary of Signing: Prevent Drainers and Harmful Approvals

Many losses come from a single bad signature when you grant too much permission.

3. Keep Hot vs. Cold Wallets Separate

Treat your wallets like bank accounts; hot ones are for daily use, while cold ones are for saving.

4. Maintain Device and Browser Hygiene

Make sure your devices and browsers are secure and regularly updated.

5. Double-check Before Sending: Addresses and Chains

Always verify addresses and networks before executing any transactions.

6. Defend Against Social Engineering Scams

Scams often rely on human interaction rather than sophisticated tech.

7. Prepare for Recovery: Make Mistakes Manageable

Have a plan for potential errors to minimize losses.

If something goes wrong, act quickly by transferring assets to a new wallet and contacting authorities with all pertinent details to increase the chances of recovery.

Start implementing these security measures now to protect your assets from potential future threats.
