In Bitcoin, a little paranoia isn't a flaw — it's a survival trait. Verify your firmware. Check the address twice. Trust nothing you can't confirm yourself. This ransom-note-style tee wears that mindset proudly, a nod to the hard-won wisdom that the people who question everything are the ones still holding their coins when the dust settles. Don't trust. Verify. Then verify again.

It's built for the security-obsessed corner of the community — the node runners, the multisig diehards, the OPSEC-minded folks who cover their webcams, compartmentalize their stack, and read the changelog before they update. If you're the type who thinks in threat models and treats operational security as a lifestyle, not an afterthought, this one's for you. Wear it to meetups and conferences where "how do you store your keys?" is a genuine conversation, and let it signal that you take self-sovereignty seriously. Available in Autumn and Black Heather.

Here's the rundown: a mid-weight 4.2 oz./yd.² (142 g/m²) tee spun from 100% combed and ring-spun cotton, with the heather shades carrying a bit of polyester. Pre-shrunk so it keeps its fit wash after wash, and finished with side seams and shoulder-to-shoulder taping for structure that goes the distance. Blank product sourced from Nicaragua, Mexico, Honduras, or the US.
