As one would come to expect from such a service, Ran$umBin will take a cut of the fee paid for every transaction. However, the commission percentage is based on who the original data belongs to, and higher value data will invoke a higher commission percentage. Rather than dealing with victims of their hacking activities directly, internet criminals can direct the original data owners to this dark web platform to make the payment. Bitcoin is an accepted form of payment, which should not surprise that many people.
