THIS IS THE MOST IMPORTANT POST YOU'LL READ TODAY. This week, someone lost $6.6 Million in Ledger wallet drain. He bought the dip, didn't panic sell, and then one wallet switch cost him all 80 $BTC. Most drainers need your wallet to be online or need you to sign something you didn't read. So here's how to set up a wallet on a spare iPhone that goes online once and never again. 1. Buy a new, sealed iPhone The cheapest model works. Buy it from a store, never secondhand. A used phone could be tampered with before it reaches you. 2. Make a new Apple ID Use it only on this phone. If your main Apple ID ever gets hacked, this phone stays out of it. 3. Turn off Face ID and Touch ID Use a long passcode with letters and numbers. Face ID can be unlocked by holding the phone up to your face, even against your will. A 6-digit code can be cracked in about a day. A 10+ character one would take thousands of years. 4. Turn on Lockdown Mode Settings > Privacy & Security > Lockdown Mode. It switches off the features spyware usually uses to break in. Also, in your passcode settings, keep USB accessories switched off. That stops the charging port from passing data while the phone is locked. 5. Download the wallet app On your home WiFi, download an offline wallet app that signs with QR codes. Pick one that's open source. This is the last time the phone goes online. 6. Cut every connection Remove the SIM and delete any eSIM. Turn on Airplane Mode. Turn off WiFi and Bluetooth. Leave it like this forever. 7. Create your wallet Write the 24 words on paper or steel. Never take a photo of them, and never type them anywhere. If the phone dies, those words are how you get your coins back. 8. Move coins with QR codes On your normal phone, install that wallet's watch-only companion app. It can see your balance but can't spend anything. To send coins, it shows a QR code. Scan it with the offline iPhone, check the details, and approve. The iPhone shows a QR back. Scan that with your normal phone, and the transaction goes out. Your keys never leave the offline phone. 9. Store it switched off Turn it fully off before putting it away. A switched-off iPhone is much harder to break into. Every few months, charge it to about 50%. A battery left dead for years can get ruined. It takes one afternoon. After that, your keys never touch the internet again. Save this for later.
