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?
This is a very necessary precaution of which i support. There is a possibility that this is already on going. Even though it is going to be a difficult task to take down cryptocurrency entirely, precautions are necessary.
