In October of 2013, Ross Ulbricht was arrested for his involvement in the Silk Road marketplace. The Silk Road was an online black market that allowed users to buy and sell illegal drugs and other contraband using the Bitcoin digital currency.
At the time of Ulbricht’s arrest, the Silk Road had generated over $1.2 billion in sales and had earned Ulbricht a commission of 6% on all sales.
At the time of his arrest, Ulbricht’s personal Bitcoin wallet contained over 700,000 Bitcoins, which were seized by the FBI. These Bitcoins were worth over $140 million at the time of seizure and are now worth over $4 billion.
It is believed that Ulbricht acquired most of his Bitcoins through the Silk Road marketplace.
