#CryptoSecurity101 Crypto security is critical to protecting your digital assets. Here’s a concise guide to the basics:
Secure Your Private Keys
Private keys are your access to your crypto. Never share them.
Store them offline in a hardware wallet (e.g., Ledger, Trezor) or a paper wallet.
Avoid keeping keys on internet-connected devices or cloud storage.
Use Strong Passwords and 2FA
Create unique, complex passwords for crypto exchanges and wallets.
Enable two-factor authentication (2FA), preferably with an authenticator app (e.g., Google Authenticator) or hardware key, not SMS.
Choose Reputable Platforms
Use well-established exchanges and wallets with strong security records.
Research platforms for past hacks, user reviews, and transparency (e.g., proof of reserves).
Avoid obscure or unverified platforms promising high returns.
Beware of Phishing and Scams
Verify website URLs and email senders. Scammers often mimic legitimate platforms.
Never click links or download attachments from unsolicited messages.
Be skeptical of “too good to be true” offers or giveaways.
Keep Software Updated
Regularly update wallet apps, exchange software, and your devices to patch vulnerabilities.
Use antivirus software and a firewall to protect against malware.
Cold Storage for Long-Term Holdings
Store most of your crypto in cold storage (offline) to minimize hacking risks.
Only keep small amounts in hot wallets (online) for daily use.
Backup Your Wallet
Save your seed phrase (12-24 words) securely offline, ideally on metal or paper.
Split backups and store them in multiple safe locations (e.g., safe deposit box).
Never store seed phrases digitally.
Stay Anonymous
Avoid sharing your crypto holdings publicly to reduce targeted attacks.
Use privacy-focused coins or mixers if anonymity is a priority (but research legal implications).
Monitor Transactions
Regularly check your wallet and exchange activity for unauthorized transactions.
Set up alerts for unusual activity on supported platforms.
