So much misinformation...
NSA mathematicians detailed “digital cash” two decades ago
The NSA were not the only one researching in this area. A lot of Bitcoin's building block have been studied in academia for decades, most of which were independent researchers or had roots in the cypherpunk movement of the early 90s. This has little to do with the NSA.

There's pretty much no crypto whatsoever that hasn't been touched by the NSA at one point or another. Without the NSA we likely wouldn't have crypto in the first place. And without computer activists and hackers we wouldn't have secure, widespread, public crypto as we know it today. Or cryptocurrencies, for that matter.
Think cryptography is bulletproof? Think again…
The sidechannel attack mentioned in this section has nothing to do with Bitcoin. Hell, it doesn't even have to do with cryptography.
Quantum computers are not magic devices that suddenly break everything. Worst case, quantum computers manage to derive the private key from the public key of an address, the latter which is not known until a transaction has been made -- hence, single-use BTC addresses, as by the original design, are unlikely to be affected by quantum computing.
Gotta love the conclusion though. I mean it sounds like the worst Sci-Fi movie ever, but it would make for a fun South Korean flick to watch while being stoned.
