Yeah, if there are regulations related issues, a mixer may shutdown but not without some information to its users. I am just particular about a shutdown unawares or suddenly with no effort to communicate with users in just a little way to reduce unnecessary negative speculations about the mixers reputations
if they are about to shut down i do not think keeping their users in the dark will still do much for their reputations maybe they are prolonging announcing it to their customers because they were still hoping to have fixed the problem and their customers never have to know about it or maybe they plan on taking all the money from the users as much as they can profit still in mind until the very last second before they shut down it is incredibly unfair to their users and just highlights the importance of transparency and communication
To gain continuous support and trust from any mixers on the crypto space, there should be team's concerns that users should be aware of certain issues because crypto is a community driven ecosystem and without the community there may not be continuity of the mixer platform.
In my opinion, there shouldn't be any hidden agenda when it comes to shouting down without a little information to users, it might be suspicious, there are better ways to related certain information especially on issues that may be beyond management control.
in a nutshell, I am always confidence that we have mixers that have been doing business without some these unforseen challenges that may lead to sudden shutdown, unawares to users. Good to have the Coinomize biz on the mixers space for over five years.
