Call centers who employ people to scam the elderly have nothing to do with this case. eXch didn't scam anyone. It operated as advertised. It was an instant cryptocurrency exchange that anyone could use without going through KYC or AML checks. Who you are and what you do with your money isn't and shouldn't be their concern. If the exchange was used by criminals, then go after those criminals, build your case, and arrest them. The world wasn't unsafe with eXch around and it won't be any safer with them gone.

If you work in a supermarket and a thief comes and buys something, should the police close the market down and arrest the manager and staff because they allowed a criminal to buy his food there? They should not.
