How to Keep Your Crypto Safe: Basic Security Practices (No Investment Advice)

Simple habits can dramatically improve your crypto security.

Crypto security isn’t complicated, but it does require a plan and consistent habits. This beginner-friendly guide covers wallet types, passwords & 2FA, seed phrases, device hygiene, and common scams. Educational content only — no investment advice.

Quick Safety Checklist

• Use a hot wallet (mobile/extension) for small, daily use only.
• Consider a hardware (cold) wallet for long-term savings.
• Create a long, unique passphrase and enable 2FA via an authenticator app (avoid SMS 2FA).
• Write your seed phrase on paper/metal and store offline (no photos/screenshots/cloud).
• Send a test transaction before large transfers.
• Avoid public Wi-Fi for wallet activity; keep devices updated.
• Ignore giveaways, “send 1 get 2 back,” and fake support requests.

Wallet Types: Hot vs Cold

Hot wallets (apps/browser extensions) are connected to the internet—fast and convenient, but more exposed. Cold wallets (hardware or offline backups) stay offline—slower but far safer for long-term storage.

Feature	Hot Wallet	Cold Wallet
Connection	Online	Offline
Best For	Daily spending, small amounts	Long-term holding (savings)
Risk Level	Higher (phishing/malware risk)	Lower (physical custody risk)
Ease of Use	Very easy	Needs setup & device

Passwords, Passphrases & 2FA

• Use a long passphrase (12–16+ chars). Pattern idea: Noun-Verb-RandomNumber-Symbol
• Store credentials in a reputable password manager.
• Enable two-factor authentication using an authenticator app (not SMS).

Seed Phrase: Golden Rules

Do	Don’t
Keep paper/metal backups offline (two copies in different safe places).	Never take a photo or screenshot of your seed phrase.
Use a discreet label (avoid words like “seed” or “wallet”).	Do not store in email, cloud drives, chats, or notes apps.
Prepare high-level recovery instructions for emergencies.	Never enter your seed phrase on websites or with “support agents.”

Rule #1: You can share your public address; never share your private key/seed.

Device Hygiene (Basic but Powerful)

• Keep your OS, browser, and wallet app updated.
• Remove unknown browser extensions; use the minimum required.
• Download wallets only from official websites/app stores.
• Avoid public Wi-Fi for wallet actions; if necessary, use a trusted VPN.

Common Scams to Avoid

• Fake Support: Anyone asking for seed/OTP is a scammer.
• Giveaway/Airdrop Traps: “Send 1 get 2 back” is always a scam.
• Approval Phishing: Don’t grant unlimited spend approvals to unknown dApps.
• Imposter Sites: Double-check URLs; use bookmarks for important services.

Before You Send Crypto: Do a Test

1. Verify the address (check beginning and ending characters).
2. Send a small test amount first; send the rest after confirmation.
3. Select the correct network (e.g., ERC-20 vs BEP-20) and fee settings.

Emergency Recovery Plan

• Maintain a non-sensitive inventory (wallet types, devices, where backups are stored).
• Keep discreet hints for the backup location (avoid explicit labels).
• Choose a trusted person and provide high-level guidance (never give the seed directly).

FAQs

What’s the basic difference between public and private keys?

The public key/address is shareable to receive funds. The private key/seed authorizes transactions and must remain secret.

Do I really need a hardware wallet?

If you hold meaningful long-term funds, a hardware wallet can significantly improve security. For small, daily use, a hot wallet is fine.

If I lose my phone, are my funds gone?

No — if your seed phrase is backed up safely, you can restore the wallet on a new device.
