Is Bitcoin's encryption more vulnerable to quantum computing than we thought? A new Google paper says the threshold to crack elliptic curve cryptography dropped from 20 million qubits to just 500,000. Sam Lyman, Zack Cohen, Zack Shapiro and Ken Egan from the Bitcoin Policy Institute discuss the geopolitical implications, the race between developers and institutions to lead Bitcoin's quantum upgrade, and why "not your keys, not your coins" is about to be tested like never before.
