is this a crypto insurance service, whether this service can be trusted, is there any evidence about this service, I doubt about this service how they do it, and whether fees will be charged if using this service?
It doesn't look like an insurance since you will be acquiring their service after the crime has happen or your crypto has been stolen not before. So this is what they call I think is a "private investigator" for people who don't see any kind of progress with the authorities. The downside of course is you will have to pay a fee and even if their service is paid there is no guarantee that the investigation will turn out well and they will recover your funds. So right now I'm more interested with the results or the success rate they have to see if they are really worth trying after all you will be paying for their services.
