I agree with you. However, the main problem is that they stopped paying back the stolen funds, this being their second lie. First was that at beginning of 2018 every client will be fully reimbursed by that time. After, they said they will pay each month a small part, instead of paying back everything in a single installment.
A company that suffered the kind of losses that NiceHash suffered, would say anything to ensure that they were able to fend off as much as possible attacks they can at the moment which is what they have done. The point is the funds stolen does not only involve investors funds but also their own working capital which would drastically affects their operation and also responsible for them not to be able to meet up with their liabilities. Now that its seemingly impossible for them to pay, they would not come out to make the announcement because it would only open them to series of liabilities and they surely don't have money to hire lawyers especially if its a class action. So, aside from the tough operating conditions, they would still continue to struggle into the future.
