Yes, sometimes it's down and sometimes working again since yesterday afternoon. What can I do now? Police didn't give any feedback yet, and told me they are in Hong Kong. They probably won't do much if it is overseas.
Since I have already answered a similar question in another topic, I will quote my answer here as well.
If you are a victim of a scam involving cryptocurrencies, or hacking, the proper course of action would be to gather all relevant information available to you and then contact professional investigators, as already suggested in this thread. Many of these services can help with every aspect of recovery. These include investigating, assisting law enforcement with subpoenas, and even testifying in court on your behalf. Each country has its own reporting mechanism for cyber-crimes such as crypto fraud. In the United States, for instance, you can report the crime to the Internet Crime and Complaint Center (
www.ic3.gov) or file a complaint at your local police station. EC3 is Europol's division to fight Internet crime in Europe, and you can use their website to find the right reporting mechanism for your country,
https://www.europol.europa.eu/report-a-crime/report-cybercrime-online.
So, depending on where you live, it is best to contact an appropriate law enforcement agency that deals with internet crime in your country.
For instance, in the United States, the FBI maintains a website which gives general information about how to report criminal activity, as well as links to several "Internet Crime Complaint Centers" around the nation, in the United Kingdom, The National Cyber Security Centre maintains a website for reporting criminal activity on the Internet, etc.
