Despite recent claims that bitcoin is becoming less popular for illicit dealings on the dark web, investigations show that it is still the payment method of choice for many. The most recent example comes from the US Navy, where a few entrepreneurial cadets reportedly used bitcoin to buy drugs which they distributed to their classmates for profit. US Navy investigators have uncovered an alleged drug ring at the U.S. Naval Academy in Annapolis, Maryland, involving between ten to two-dozen suspects. Three cadets are accused of buying cocaine, ketamine and LSD on the dark web using bitcoin and selling the drugs to their classmates. The investigation reportedly began nearly three months ago after one midshipman informed the authorities about the drug trade on the base. The top brass ordered a surprise drug test for all 4,500 cadets before dawn on Wednesday morning and DEA drug-sniffing dogs discovered cocaine in the room of one of the suspected users. The cadet suspected of owning the cocaine was at athletic practice at the time and she reportedly made a run for it but was caught and taken in for questioning.
