Alternatively you could argue bitcoin is great for cross border payments and for under cover and covert operations because it's pseudonomous. It's also an open ledger owned and controlled by Noone in particular but it is technically possible to spy on it but only the best in the world are able to and the US is leading which gives them an advantage over others (I don't know if US is leading in chain analytics but I assume so) but let's be honest the US government already know about this angle so why invite someone that is not a particular expert in this spying and cov ops area to give it? They would want to hear this from the cia and fbi themselves.
