I am going to take a shot too.
1. The gov holds onto the btc it has as a security measure.
2. A black swan event causes hyperbitcoinization.
3. The supercomputers will be dedicated to cracking 256 but encryption.
4. Lost wallets will be drained and controlled.
5. Back to square one where one of the dominant currencies is controlled by the gov.
6. But it’s just the beginning of decentralized currencies.
