Your Blueprint for True Crypto Wealth Protection
Best practices for securing crypto assets against hacks and fraud.
The mantra "not your keys, not your coins" is the cornerstone of crypto philosophy, but how do you practically live by it? Enter the 90/10 Rule, a simple yet powerful strategy for securing your digital wealth. It’s the art of balancing iron-clad security with necessary market accessibility.

Why the 90/10 Split is Non-Negotiable
Centralized exchanges are fantastic for trading but represent a single point of failure. History is littered with examples of hacks, freezes, and platform collapses where users lost everything. The 90/10 rule mitigates this catastrophic risk. Your 90% in cold storage is your sovereign wealth—immune to exchange breaches. Your 10% on an exchange is your operational fund for seizing opportunities.
Your 90%: Fort Knox in Your Pocket
This is your long-term, buy-and-hold allocation. Its home is in cold storage—a hardware wallet like Ledger or Trezor that keeps your private keys completely offline and away from internet-based attacks.
· Action 1: Purchase Wisely. Only buy hardware wallets from the official manufacturer's website. Third-party sellers risk supplying tampered devices.
· Action 2: The Immortal Backup. Your seed phrase is your master key. Write it on a metal backup plate, not paper. Store this in two separate, ultra-secure locations (e.g., a safe and a safety deposit box). Never digitize it—no photos, no cloud notes.
· Action 3: Verify Receive Addresses. Always double-check receiving addresses on your hardware wallet's screen before transferring your 90% in. This defeats malware that alters clipboard addresses.
Your 10%: The Strategic Trading Desk
This portion lives on a trusted, secured exchange like Binance. Treat it strictly as a trading desk, not a bank.
· Harden Your Account: Enable Google Authenticator or Authy for 2FA (never SMS). Activate Withdrawal Address Whitelisting and set an Anti-Phishing Code.
· Mindset is Key: Understand that you are accepting smart risk for liquidity. Rebalance the portfolio periodically, moving profits from your 10% pool back into your secure 90%.
1. Primary Storage Strategy (90/10 Rule)
Experts recommend a "tiered" security model to balance safety and accessibility:
Cold Storage (90%): Keep the vast majority of your assets in a hardware wallet (e.g., Ledger, Trezor). These devices store private keys offline, making them immune to remote hacking attempts.
Hot Wallets (10%): Use software wallets (e.g., MetaMask, Trust Wallet) only for active trading or daily transactions. Never store life savings in a hot wallet, as they are permanently vulnerable to malware and phishing.
2. Seed Phrase Security
Your seed phrase is the master key to your funds; losing it or revealing it means total loss.
No Digital Storage: Never store seed phrases in cloud services, email, notes apps, or password managers. Even screenshots are high-risk.
Metal Backups: Use stainless steel or titanium backup plates to protect against fire, water, and physical decay.
Physical Protection: Store backups in geographically separate, secure locations like a fireproof home safe or a bank safety deposit box.
Passphrases: Add a "25th word" (passphrase) to your 24-word seed. This creates a separate "hidden" wallet that remains secure even if the primary seed is found.
3. Account Access & Identity
Hard Authentication: Enable Two-Factor Authentication (2FA) on all exchange and wallet accounts.
Avoid SMS: Hackers can intercept SMS codes via SIM swapping.
Use Apps/Hardware: Prefer authenticator apps (e.g., Google Authenticator) or physical security keys like YubiKey.
Biometrics: Where available, use fingerprint or facial recognition as an additional layer of local access control.
Password Management: Use long (15+ characters), unique, and complex passwords generated by a reputable manager (e.g., 1Password, Bitwarden).
4. Advanced Technical Defenses
Multi-Signature (Multi-sig): For large holdings, use wallets that require multiple private keys (e.g., 2-of-3) to authorize a single transaction, eliminating a single point of failure.
Burner Wallets: Use separate "burner" wallets for airdrops or testing new DeFi protocols to isolate your main funds from potentially malicious smart contracts.
Token Approvals: Regularly review and revoke unused dApp permissions using tools like Revoke.cash to prevent old contracts from draining your wallet.
Withdrawal Whitelists: On exchanges, enable "whitelisting" so funds can only be sent to your pre-approved cold storage addresses.
5. Vigilance Against Fraud
Manual Verification: Always verify contract addresses on official project websites. Never trust links from Discord, Telegram, or social media DMs.
Beware "Support": Legitimate companies will never ask for your seed phrase or private key.
Public Wi-Fi: Avoid transacting on public networks. If necessary, use a high-quality VPN to encrypt your traffic.
The Bottom Line: Peace of Mind
The 90/10 Rule isn't just about allocation; it's a mindset of proactive sovereignty. It ensures that even in a worst-case scenario with an exchange, your vast majority of wealth remains untouched. In crypto, the greatest asset isn't just your portfolio—it's your security and peace of mind.

Hardening Your Exchange Account: Beyond Just 2FA
This topic focuses on securing the assets you must keep on centralized exchanges like Binance, where account takeovers are a common risk.
· Why It's Critical: Most user losses on exchanges come from "user-targeting" attacks like phishing and SIM-swaps, not platform hacks. Proper account settings are your first line of defense.
· Essential Security Checklist:
· Use an Authenticator App for 2FA: Avoid SMS-based 2FA, which is vulnerable to SIM-swapping.
· Enable Withdrawal Address Whitelisting: This restricts crypto withdrawals to only pre-approved addresses you control.
· Set an Anti-Phishing Code: This helps you identify genuine Binance emails.
· Review Login History & Device Management: Regularly check for unauthorized access and remove old devices.
· Key Insight: Treat exchange accounts as a trading desk, not a bank vault. The convenience of quick trading comes with the understanding that Binance controls the keys, and regulatory actions can affect access.

Spotting & Avoiding 2026's Top Crypto Scams
This topic educates users on identifying sophisticated modern fraud, which is crucial as scammers increasingly use AI and target new investors.
· Why It's Critical: Crypto fraud losses in the U.S. alone hit $9.3 billion in 2024. Fraudsters use advanced tactics, including deepfakes and synthetic identities, making scams harder to spot.
· Red Flags to Watch For:
· Investment/Phishing Scams: Unsolicited offers with guaranteed high returns, fake customer support agents asking for your seed phrase, or cloned websites.
· Money Laundering Patterns: Rapid movement of funds through multiple wallets, use of privacy mixers/tumblers, or transactions structured just below reporting thresholds.
· Actionable Defense:
· Never share your seed phrase or private keys with anyone, for any reason.
· Verify all website URLs and official contacts directly from the project's official social media or GitHub.
· Be skeptical of "urgent" opportunities that pressure you to act quickly.
How to Implement These Strategies
To help you get started, here is a summary of key actions from the topics above:
Self-Custody & Storage
· Use a hardware wallet for long-term holdings
· Follow the 90/10 storage split strategy
· Back up seed phrase on metal, not digitally
Exchange Security

Scegliere il portafoglio crypto giusto è una delle decisioni più importanti che prenderai come utente crypto. I portafogli non conservano solo i saldi su uno schermo: proteggono le chiavi private che ti danno il controllo sui tuoi beni. Il tipo di portafoglio che scegli influisce direttamente su quanto siano sicuri i tuoi fondi e su quanto facilmente puoi accedervi.
A un livello elevato, i portafogli crypto rientrano in due categorie: portafogli caldi e portafogli freddi. Ognuno ha uno scopo diverso e comprendere i loro compromessi può aiutarti a costruire una configurazione che soddisfi le tue esigenze.

Crypto persa = andata per sempre.
I truffatori sono più intelligenti.
Gli hacker sono più veloci.
Ma TU puoi comunque batterli.

Ecco la tua guida semplice e potente alla sicurezza del portafoglio crypto nel 2025 👇

🧠 Prima, conosci i tipi di portafogli:
1. Portafogli a caldo (online):
Veloce, connesso 24/7
Esempi: MetaMask, Trust Wallet
Rischio: Obiettivo più facile per phishing/malware
2. Portafogli a freddo (offline):
Hardware simile a USB (Ledger, Trezor)
Non connesso = molto più sicuro
Migliore per HODLing a lungo termine
3. Portafogli custodial:
Portafogli di scambio (Binance, Coinbase)

Un tipo di portafoglio di criptovaluta chiamato "portafoglio di conservazione a freddo" è realizzato per mantenere le chiavi private offline, aggiungendo un ulteriore grado di protezione contro virus, hacking e altri rischi per la sicurezza. Per accedere e controllare le partecipazioni in criptovaluta, sono necessarie chiavi private. I portafogli freddi aumentano la difficoltà per gli attori ostili di accedere alle tue risorse digitali tenendole offline.
