Most people think “crypto” means blockchain. Big public ledgers like Bitcoin and Ethereum where every transaction is stamped into eternity. But blockchains were never designed for privacy. They're loud by default. Transparent by design. Every payment is a broadcast. Every balance, a public file.

That might be fine in clean systems. But in cyberpunk economics — messy, low-trust, and full of watchers — broadcasting your entire financial life is not just unnecessary. It’s dangerous.
