About this site

CatBitcoin explains one specific, current technical question calmly: what quantum computing actually means for Bitcoin today, versus what it might mean eventually. No price talk, no predictions, no hype in either direction.

Why a cat

Schrodinger's cat is a genuinely useful way to think about an unspent Bitcoin address: its public key exists in a kind of undetermined state until the moment you spend and observe it on-chain. The mascot is playful; the content underneath it is not.

How we write

Claims here are checked against what's publicly reported about the relevant research and proposals. Where the timeline or a specific detail is genuinely uncertain, and in quantum computing it usually is, we say so rather than picking a confident-sounding number.

The tools

The wallet checker queries a public block explorer to look up real on-chain data about the address you enter; that's a real network request, and the page says so plainly. The sats converter is pure offline arithmetic.

How the site pays for itself

Some pages link to hardware wallets or security tools relevant to the topic, and the site may earn a commission if you buy through one of those links. Nothing here is investment advice, and the site never recommends buying, selling, or holding anything as an investment.

What this site doesn't do

No price predictions, no timeline promises dressed up as certainty, and no pushing you to move funds preemptively out of fear. Quantum risk to Bitcoin is real as a long-term engineering question and not remotely an emergency today; if a page ever reads like it's rushing you toward a decision, that's a bug, not the intent. The goal is calm, specific information you can act on at your own pace, or not act on at all.
