They should care for it or they will end up grabbed by laws and shut down - my personal views as I have seen some good mixers being shut by not abiding by the laws, though I know CM knows their job better and they are my personal favorite.
Yeah man, they will also probably just implement KYC to avoid getting shut down by the gov, right? Rofl.
I never said that but then such a service will only help criminals to get their tainted Bitcoins or BTC gained through criminal activities shuffled by them and have them saved. I bet they currently have the choice of helping out in such cases as they have got all the details in the end like transaction timestamps, id's and everything as well as the transactions that they sent? No?
Which is a slippery slope, and something that would make Chipmixer totally untrustworthy. What's next, you want Chipmixer to give every Bitcoin coming from Casinos, Darknet markets, bounty campaigns (yes most of those can be considered illegal too, and non-registered exchanges (yobit)) to authorities?
The same analogy that you're using on Chipmixer can also be used on the service you're advertising:
The service you're advertising with "No KYC verification" will also only help out criminals who are looking to cash out their "hacked" Ethereum, and yours is even worse considering it's a gateway to real money, whereas Chipmixer is simply a shuffler. Why are they not introducing forced KYC on every customer like LocalBitcoins does?
Besides, even if they would help authorities out, it would still be useless, as it won't sway their opinion of them, namely what you described; them being a service for criminals.
