I saw someone’s wallet was hacked again. No matter how many times I say this, it’s never enough. Let’s review the common ways wallets get stolen.

**Avoid These Three Major Traps: Secret Phrase Leaks, Phishing Sites, Fake Customer Service**

First, let’s talk about the high-risk operation—

**Can you use a fingerprint browser?** Yes, but with conditions.
It must be used with a hardware wallet! This way, the private key will never be exposed in the browser environment. Multiple browser instances do support connecting hardware wallets, so don’t think that opening multiple browsers means you can’t use cold wallets.

The only exception: browsers used for testing network scripts, which originally contain empty wallets. But now, testnet airdrops are over, so probably no one is using them as slaves anymore.

**Here’s the key—environment isolation**

The most ideal solution? Get a Mac or Linux laptop dedicated to on-chain activities.
But considering cost and daily efficiency, simply installing a virtual machine is enough. VMware is now free, and Windows’ built-in Hyper-V works too. Don’t think it’s complicated; a tech novice can set it up in an hour. Preferably choose Ubuntu as the OS; if not, Windows will do.

**Virtual machine setup checklist (follow these steps):**
- After installing the OS: turn off clipboard synchronization
- Install only three things: Chrome browser + Scam Sniffer (blocks phishing sites) + a mainstream wallet plugin
- Don’t install any other software
- Remember to regularly update system patches

This virtual machine only does one thing—
