It seems so. They're fairly new to me, so I wouldn't pour large amounts of crypto on them just to be safe. I'm glad there are alternatives out there in order to help protect people's privacy. Just because crypto mixers exist, that doesn't mean they're solely used for malicious purposes. People have many legitimate reasons to use a mixer, especially when they don't want third parties spying on their transactions. Businesses need privacy to help protect their utmost sensitive information, so I don't get why the government is completely against crypto mixers.
I get the government wants to stop money laundering and tax evasion, but taking down the mixer completely by sanctioning it is not the ideal path to take. Instead of sanctioning mixers, why doesn't the US government sanction the individuals using the mixers for illegal activities? I'm pretty sure this will be challenged at the court soon (if it hasn't already), so only time will tell us what lies ahead for crypto/Blockchain tech's prominence in the mainstream world. Just my opinion
