What is the Bitcoin quantum threat?

Bitcoin's encryption relies on math quantum computers can shatter, exposing private keys from public ones during transactions.

When will quantum computers break Bitcoin?

Nobel physicist John Martinis estimates 5-10 years, but engineering hurdles could stretch it—still, prep now.

How can Bitcoin go quantum-resistant?

Via protocol upgrades like post-quantum signatures, but slow governance means consensus battles ahead.
