As a developer i interested to develop some platform like crypto mixer, but i don't really know if it still profitable or not at this trend, any clue?
before everything else , I would like to advise you that Mixers or mixing company advertisements and links are already banned in this forum so better try not to break that rules.
and about your question? the US government is running against some mixing company and I believe that they wanted to shut down everything that hides identity of crypto users specially in their region.
