## Resource

"Paper is where Bitcoin goes to die." James Caruso — co-founder and VP of Stamp Seed — joins the show with one of the most unlikely origin stories in Bitcoin: how a 70-year-old metal-stamping company stumbled into Bitcoin through its own search data, and became one of the most trusted cold-storage backups in the space. We get into why paper — and the gel pen you wrote your seed words with — is the weakest link in your stack, why titanium, what's actually in the box, and James's arc from get-rich-quick Robinhood trader to "it could drop 40% and I'm just buying more" conviction. Then the cold-storage deep end: single-sig versus multisig, planning for your heirs, and the most creative hiding spot we've ever heard — a seed plate disguised as a rock, sunk in a backyard pond. No batteries. No firmware. No third-party trust. Just a titanium-sized post-it.
