I think it has a good and bad impact to the bitcoiners. If NSA only track those bad and illigal activities in crypto then it is good but if NSA wants to track every bitcoin users for their own good and to force people pay tax then it is bad because bitcoin users has the right to hide their identity because bitcoin has a nature of anonimity.
