Many people are criminals in disguise and they are ruining bitcoin name by scamming people using Bitcoin as if it is a safe pass to scam people for free and get away with it, so no wonder that the government hates Mixers and privacy in this space, who is to be blame if not for our people who are criminals in disguise?
The world can never be a better place for scammers because they see opportunity to swindle people their money when they get the chance but you are talking about Bitcoin because you see it and it's been discussed, do you know the magnitude of fiat scams that is happening every day? Do you know how terrorism is been funded with fiat? Do you know how many fiat that is been stolen under the government every day? You don't see them because the government doesn't report that to you.
Not all Bitcoin investors are real investors, some are just hiding and pretending to be Bitcoin real investors, even if they are close to you, it doesn't mean they are clean, many good people want privacy and mixers to prevail but I wonder how when bad people are taking advantage of these features to steal from others.
Scam originated from fiat, a lot of people are scam from fake dating, money washing, fake investment and many more. Read the story of Hushpuooy, you will understand how that guy was able to scam people using fiat and guess what, government never caught him for once not until he started showing off his wealth on Instagram, if that was Bitcoin transaction, people would have know the source and the final place it was spent.
