My friend is using cryptomixer .io since many years without any problems. Check first to which server IP points the URL. And then check the IP address with an whois (for example
https://www.heise.de/netze/tools/whois/)
I would not trust a mixer which server IP is in the US. The US is against privacy and is treating mixer owner like criminals
