Maybe they know that there is a halving next summer and they probably believe that bitcoin's price will increase after halving, so, they prefer to HODL? I am just joking but since they have access on that wallet, why should they be in a hurry to transfer coins? Price is not at its highest, also, if they transfer coins right now, they will attract a lot of unwanted attention but if they let it die and transfer coins year(s) later, it won't become a hot topic but if they do it today, it will become.

So, as he says, even such a massive signature campaign with top users didn't bring them customers? If that is true, then how do other mixers like Sinbad, YoMix, Mixtum and Coinomize are able to pay thousands of dollars weekly for months and months? Can you confirm that sig campaign didn't work for them? I wonder, how do you track results.
Btw there are other companies like BestChange, crypto.games, Roobet, Rollbit, Freebitco and others that run signature campaign for years and still continue to keep it active.
Something must have happened since then. They would have reached the forum as soon as they reached their destination. If this email conversation happened in August, then probably something bad must have happened to them.
I had to travel and there was no one with authority to do things, doesn't really make sense. Also, when you run such a business, you have to be sure that either things run very smoothly or you have a trusted person who will take care of things instead of you or you don't travel and stay where you are!
I believe it was a scam exit. When someone wants to shut down service, they put a warning on their website and whirlwind hasn't done that.
