This would undermine the digital dollars’ ability to act as a value-measuring tool. Maintaining the scarcity of digital dollars requires a central authority. Keeping a useful record of value transfers digitally used to require trusting a bank.
Reliable statistics on the number of drug-related murders in the United States are hard to come by. A 1994 Department of Justice report suggested that between a third and a half of U.S. homicides were drug-related, while a recent Center for Disease Control study found that the rate varied between 5% and 25% (a 2002 Bureau of Justice report splits the difference). Part of this variance is that "drug-related" murders are hard to define. There are murders committed by people on drugs, murders committed by addicts to get money for drugs, turf-war murders by drug suppliers, and murders committed by gangs whose principal source of income is drug sales.
