If that happens it will again be a huge blow for DNMs. If you read the final message of Bitmixer before shutting down, you would have a feeling that something went on before deciding to close it down.
It makes no sense to close a profitable service which they believed in.
Do your illicit transactions with XMR and cashout to BTC/USD to avoid the need for a mixer. Why use a centralized mixer when you can use a proof-of-work backed blockchain?
