To make matters even more worrying, there are other ways to make money with Bitcoin ransomware as well, by offering more customization. Some websites let users enter their own Bitcoin address, how much ransom they want to charge, and the time period users have to make the payment. Once everything is configured, the user can then download the complete package in exchange for a small price. Although this solution is not too refined, it does the job well.
