Teen Admits to Teaching Bitcoin to ISIS

A Virginia teenager pleaded guilty Thursday to providing material support to ISIS. Authorities say Ali Shukri Amin helped an 18-year-old man travel to fight with the terrorist group and advocated for it by using the Twitter handle @AmreekiWitness. Prosecutors also said the 17-year-old wrote about ISIS evading detection by using bitcoin or other forms of online currency that are harder to track. By the time his account was shut down, Amin had tweeted more than 7,000 times and had more than 4,000 followers.
