We only write about whether a Bitcoin address has already shown its public key.
CatBitcoin exists to say one sentence clearly: until you spend from a hash-based address — or you used Taproot — the public key is in the box. Why the cat is the manifesto. The checker is how you look.
How we write
Claims are checked against public research and proposals. Where a date or qubit count is genuinely uncertain, we say so. The metaphor has a limit: this is classical one-way hashing, not quantum superposition. We keep that limit in view.
The tools
Schrödinger's Wallet queries a public block explorer for spend history. That is a real network request, disclosed on the page and in privacy. There is no sats converter and no halving clock here. Those were generic Bitcoin toys. They did not earn the name.
How the site pays for itself
Some pages may link to hardware wallets or security tools and earn a commission if you buy through a link. Nothing here is investment advice. The site never tells you to buy, sell, or hold coins as an investment.

Quick answers
- Why is this site called CatBitcoin?

- Do you give investment advice?
- No. No prices, no buy or sell calls.
