Anonymous coins will never be accepted in countries like China. Look how restrictive they are with something that can be tracked. Likely, many other countries including the United States will ban them if they ever become popular. Just think about it, the policing agencies will never accept not being able to track drug money. It's that simple. Anyone who thinks otherwise is just delusional. Anonymous coins are the riskiest to own because when the hammer comes down they will be nearly worthless.
The "follow the money trail" approach. But coins are mixable. Fun fact: This is how we do it, using bitcoin, since ages.
Deeponion actually never was needed.
What icks me more is the "follow the postoffice trail" approach. If any household ordered a parcel AND some tor network useage has been logfiled during the last monthes from the internet access of this household, the parcel gets inspected. Plain simple.
VPN useage getting filed as tor useage.
