Bitcoin mixers have a long history since they came into inception some time ago. They've been a viable alternative for people looking towards privacy within their Bitcoin transactions. While Bitcoin mixers are far from being perfect, they're still one of the best solutions for obfuscating transactions from third parties. The only concern would be that mixing services are centralized as they're provided by a middleman. In effect, this brings a single point of failure greatly defeating the purpose of privacy.

We've seen how Bestmixer got shut down by the authorities. They claim that Bestmixer encouraged money laundering activities which resulted in legal action. The truth is that Bitcoin mixers can be used for both good and bad things. Money laundering is mostly done with Fiat than with cryptocurrencies like Bitcoin or Ethereum. Still though, the perception of worldwide governments against mixers/tumblers seems to be different nowadays. Which makes me wonder whenever Bitcoin mixers will be considered illegal by such entities within the future?

If governments ban mixers/tumblers, then they could easily do the same to privacy-oriented cryptocurrencies like Monero and Grin. It's all a matter of power and control over people than anything else. What do you think about this?
