Ali Shukri Amin faces 15 years in prison after he used his Twitter account to send tips to ISIS about how to use the currency last year.
17-year-old Amin, from Virginia, opened the account in June last year and accumulated more than 4,000 followers.
Under the Twitter username @Amreekiwitness, Amin tweeted a blog he wrote called “Bitcoin and the Charity of Jihad”, where he explained the basics of using Bitcoin.
Writing on his blog, Amin said: “This system has the potential to revive the lost sunnah of donating to the mujahideen, it is simple, easy and we ask Allah to hasten its usage for us.”
Dubbed the “cryptocurrency”, Bitcoin is the world’s fist decentralised currency and is the largest of its kind, with millions of people trading the currency since its creation in 2008.
Bitcoins can be mined from users’ hard drives and traded across softwares.
The currency can also be sold for a centralised currency. They can also be used to make illegal purchases without being easily traced.
