No, it's not. You have no idea what you're talking about.
coboguard has nothing to do with ChipMixer. He's just trolling and maybe you are too (user registered today?)

CoboGuard admitted to be Visk (on medium.com), visk use his same profile to advertise scams like Tether-tumbler.com and bitwhisk.io.
Coboguard is also advertising for chipmixer. We can see that chipmixer uses same registar/ same uncommon extension .Io as coboguard scams.
coboguard is also behind chipmixer.com (alone or in team I have no idea) !
So, ChipMixer === CoboGuard because there is an article 2 years after its public launch from a random user talking about it? Can I create an article about Binance, scam some people and say I'm Binance's CEO, thus Binance is a scam?
Do you know of anyone who got scammed by ChipMixer after more than 3 years of their launch? Are you aware of how much money have flown through their mixer and how much they have paid for their signature campaign and forum ad slots? Have any of CoboGuard fake mixers acted like this or spent literal millions of dollars, to end up not scamming anyone? (I'm sure there would be accusations, right?)
