I have used
ChipMixer yesterday. Still waiting for my "chips", admin is offline.
Another user is complaining on
Privcoin's thread. He is probably in worse situation, because PrivCoin's admin was last online almost 3 months ago.
I believe that I will eventually get my coins from ChipMixer, when admin decide to take care of his business, but I will never again use mixers. Switching to Wasabi Wallet completely.
