I don't really agree with that logic.My impression of bitcoin is that it is complicated to trace the money. So it will draw more attention from the Government than if you were to use larger financial institutions. The smartest computer techs in the world work for the government. They will be more interested in bitcoin than someone who uses WU. Why? Terrorists, also human nature. The harder someone tries to hide something the more interested people become. They want to know why. They don't really care what. If your father hides a gun in the house, you get curious and want to look for it. If your father tells you the gun is in the closet and not to touch it, you probably wont. (bad example) but.. if its harder to find, lager smarter people will get involved. The amount of attacks nations are having and people trying to support extremist groups, trying to travel to other countries, nations are on high alert. I see AAS as less important and not a priority. Like you said, if they want to find you they will, but I feel like they are more insulted the trickier you get because they feel like someone is saying "Im smarter than you" and they need to prove you wrong. Just my thoughts, but I need to read up more on bitcoin.
The government will be more interested in someone using a VPN over plain ISP connection.
Same argument with PGP/GPG encrypted mail over non-encrypted mail.
TOR browsing versus normal browsing.
Darknet over clearnet.
Protonmail/countermail over gmail/yahoo.
Pseudonyms over real names.
And Bitcoin over WU/MG.
So, is the answer to use a gmail account, avoid PGP/GPG, stay "clear" of darknet, never use a VPN, avoid TOR at all costs, always use your real name and finally choose WU over Bitcoin?
