@Lanatsa. I predict 2 positive effects for successful government shutdowns of all mixers. It will begin the anonymous coin revolution and it might make bitcoin unattractive for criminals which makes it more attractive for today's more skeptical investors.
Bitcoin is already becoming quite unattractive for the criminals, as a lot of them are getting caught while converting the "dirty" coins back to fiat cash. For a while, anonymous coins (such as Monero, Zcash and Deep Onion) were being talked about as the preferred payment method in the dark web, but these coins never made it due to their low liquidity. I guess the criminals will soon go back to their old modes of payment (i.e those using fiat cash). Physical cash remains the most anonymous method of payment even now.
