কীভাবে সুরক্ষিত করবেন Your Crypto Exchange Account

The history of crypto is littered with devastating hacks — Mt. Gox lost 850,000 Bitcoin in 2014, Coincheck lost $530 million in NEM tokens in 2018, and FTX's collapse exposed billions in mismanaged funds.

8 Essential Security Settings to Enable Now

1. Use an Authenticator App, Not SMS

SMS-based টু-ফ্যাক্টর অথেন্টিকেশন is vulnerable to SIM swapping attacks. Switch to Google Authenticator, Authy, or a hardware security key (YubiKey). Most major exchanges — Coinbase, Binance, Kraken — support all of these.

2. Enable Withdrawal Email Confirmation

Require email confirmation for every withdrawal. Even if an attacker gains access to your account, they'll need access to your email to complete a withdrawal.

3. Set Up Address Whitelisting

Only allow withdrawals to pre-approved wallet addresses. Most exchanges enforce a 24-48 hour waiting period when adding new addresses, giving you time to catch unauthorized changes.

4. Lock Down API Keys

If you use trading bots, never grant withdrawal permissions to API keys. Delete any API keys you're not actively using.

5. Use a Unique, Strong Password

Your exchange password should be at least 16 characters and completely unique — never reused from any other service. Use a password manager to generate and store it.

6. Create a Dedicated Email

Use a separate email address exclusively for your exchange accounts. This email should not be publicly known or used for social media.

7. Enable Login Notifications

Turn on alerts for new device logins and IP address changes. Immediate notification is the fastest way to catch unauthorized access.

8. Review Authorized Sessions Regularly

Check your active sessions and authorized devices at least monthly. Revoke anything you don't recognize.

• Login links: Legitimate exchanges rarely ask you to click email links to log in
• Attachment requests: Exchanges never send attachments requesting personal info

Always access your exchange by typing the URL directly or using a bookmark — never through an email link.
