Yeh they needed loads of people to use tor to mask traffic. If I was the cia, I would fluff up the value of bitcoin to lure people looking to avoid taxes and banking systems into investing by spamming transaction volumes, then use the books to build cases against them (it's anon but every single transaction is recorded). Then either: build backdoors in aps that sent user data when using wallets, or print enough money to just buy and wipe out everyones bitcoin value overnight through a market crash. A LOT of people use autobots that sell bitcoin when it drops a certain amount so the avalanche would be insane lol. e: 1 more way to brick the wealth in bitcoin is to wait until the mining required to keep transactions records is ridiculous (it is) and then turn the power off to the mining hubs, stalling the engine out.
