In practise - time is much more valuable than money. I suggest you read about us on the Internet, we are known as "Sodinokibi Ransomware". For example, this article: https://www.coveware.com/blog/2019/7/15/ransomware-amounts-rise-3x-in-q2-as-ryuk-amp-sodinokibi-spread Pay attention to that: "How Much Data Is Decrypted with a Ransomware Decryptor? In Q2 2019, victims who paid for a decryptor recovered 92% of their encrypted data. This statistic varied dramatically depending on the ransomware type. For example, Ryuk ransomware has a relatively low data recovery rate, at ~ 87%, while Sodinokibi was close to 100%. " Now you have a guarantee that your files will be returned 100 %. [+] How to get access on website?
