This is a quote from the article;
What would qualify as suspicious? In my opinion it's either an address was involved in criminal activities or not. So proven criminal activities can be traced to Bitcoin transactions, but Bitcoin transactions should not be investigated seeking suspicious criminal activity simply on the grounds that they were made using cryptocurrency.

This could likely become a targeted attack on cryptocurrency transactions, especially when it involves large amounts. The blockchain is transparent and all transactions can be traced, so are they attempting to collate data on transactions such as wallet and IP addresses in order to break the pseudo-anonymity?
Seeking complete privacy should not be suspicious.

We need an app to detect suspicious of illicit activities by the military and governments.
