Honestly, I don't see anything justifying the term "Most Effective" when it comes to mixers, because you don't offer anything that other similar services don't offer. However, you offer something you don't list as "Key Features", which is the ability to mix ETH and USDT.

As for Switzerland, I would not agree that servers in that country provide any extra security, and I believe that the Swiss cooperate with everyone who sends them a request when it comes to possible money laundering, terrorist financing, and similar things.

Since this service is new, I recommend caution until the legitimacy of the service is established.
