0.5 BTC TO @adam3us if he can prove his cryptography chops.
I think you are a fraud.
My money is good and happy to test you.
I do not believe you are the person you pretend to be.
My word and money is good.
Prove your work.
JUST IN: NIC CARTER JUST SAID A QUANTUM "ATOM BOMB" MOMENT IS NEAR AND THAT 1,000,000 #BITCOIN IS NOW AT RISK
"BREAKING ELLIPTIC CURVES WILL ONE OF THE FIRST USES OF A QUANTUM COMPUTER"
WE MAY NOT FIND ABOUT Q-DAY UNTIL "ALL THE OLD SATOSHI COINS ARE HARVESTED"
"YOU DON'T HAVE TO TELL ANYONE. YOU CAN JUST CRACK THE KEYS AND WAIT" 👀

BREAKING: If you hold Bitcoin, this is SCARY!
Google says its Willow quantum chip reduced errors in a key process by 40 times, a major breakthrough.
In an early worst-case scenario, quantum computers could crack Bitcoin wallets by 2029–2030, just 3-4 years away.
🚨JUST IN: Google may bring Bitcoin’s Q-Day sooner than expected after its Willow chip cuts quantum errors 40x.
Google says a technique called “magic state cultivation” now works on its Willow chip, cutting errors about 40x with a record 99.99% accuracy.
Q-Day is the moment a quantum computer becomes powerful enough to break the cryptography that protects Bitcoin wallets.
Google’s own 2025 estimate for cracking RSA encryption with under a million qubits uses this same technique.
The research was published in Science, but Google says it still needs to prove the technique works at a larger scale.
