Here is my opinion about how we should proceed with this:

1. Determine the identity of the owner of bit-mining.co and of all of the principal engineers, partners and co-owners. Get their names, addresses, countries of origin.

2. Organize a master list of the contact information and amounts of loss of all those who lost funds on bit-mining.co

3. Decide from among us who will coordinate this project and get people to agree to do each of the separate tasks below, such as talking to prosecutors, lawyers, etc.
 
2. File a criminal complain in the legal jurisdictions where each of the principals live.

3. Contact the civil authority in each location and begin conversation with the criminal prosecuters for that jurisdiction.

4. I also feel someone should contact the owner of bit-mining.co and ask him to come clean.
