A lot of game theory there... every time you do something... it's a signal. What could happen if this actor do that, with the price, with the relevance of btc, with the reaction of node operators, devs, etc. It is not isolate.

What if NSA is the owner of 1M BTC (Satoshi) and in 10 year wake up... 1/21M ... lot of power, but again, it will not be an isolate signal without repercussion.
