Yes, I use Chipmixer and Monero, just like I use VPN and TOR, because I have something to hide, it's my privacy.
Why I tried to exchange ChipMixer's chip to Monero, I could explain, but does that matter?
WHAT DOES MATTER:
They have TOS, but if I wanted to settle this in court, which court have jurisdiction? They don't have company, they hide their names.
I have found that Openchange lie and hide their identities and use fake names and fake verified accounts to make payments.
They are Russians, based in Russia, speak very poor English, but they use, for example, multiple Paypal accounts with American names and addresses. And there is probably more, I'm still investigating.
They are in business for a long time, but current domain is relatively new, because their previous was seized. I still don't know all the details.
Who would send their documents and selfie and many more things they asked to site like this one?
