Seed XOR Bundle Q

For one special bundle price, you get: 1 x COLDCARD™ Q 1 x Industrial MicroSD 3 x SEEDPLATE® 24 Words 1 x Security Bag Kit

Check the bag. Check the numbers. Read the docs. Create entropy. Write down the 24 seed words. PGP the software. Create a 12 word passphrase using words from the BIP39 list. Tripple check the spelling. It's easier if you use the pre-spelled list on the Q. Use a dry erase marker to mark the spots you need to punch on your seed plates. Double check them. If you made a miatake, wipe it with a damp paper towel and fix it. When your sure it's right, punch the letters...But first...Send a small transaction. Erase your key from the cold card. Test your seed phrase recovery. Test your passphrase. Reconstruct it from your seed plates. If you see your sats, congrats. If not, kiss that small transaction goodbye and start over. Store your key and passphrase in seperate locations. Create lamintated backup(food saver bags also work), but store them somewhere far away from you. Keep learning. Assume your stack will be worth 10X more on 4 years and 100X more in 8. This is not financial advice. It is cybersecurity advice. If you fuck up, no one can help you so stay humble and stack knowledge.
