Some ideas on how it could work:
- Read through the connection data (phone,email etc) from key figures of the Bitcoin community to gain insider knowledge
- Infiltrate core development and replace Bitcoin key figures with NSA staff
- Discredit respected members of the community
- Kill people, if they don't corporate.
Are core devs discussing this possiblility of a large scale infiltration and how to avoid?
As crazy as it may sound, the NSA can send a giant computer virus that will target the blockchain. Bitcoins need the blockchain, so when the blockchain is in jeopardy, then the NSA got us on our balls. But this will definitely take a couple of years to do so as of now, we can take advantage of bitcoins.
