I think that if there is really a mixer that inspires trust, it's Cryptomixer.io without a doubt.
Not even without a doubt, come on. I mean, I had to search that thing. 
My point is that using an old or new mixer is not enough if privacy is a top priority. Yes, aged Tumbler company is a top priority but to be safe it's better to use 1 or 2 privacy services after using a mixing site. I made this statement based on advice once provided by Theymos "You should always operate with the expectation that any anonymity system you use will eventually fail you. "
After operating like that, is when you get a totally clean coin and the right privacy.
Yes, I agree with you on that. Just using a mixer is not completely enough today to protect your privacy and when protecting your privacy, you should always low self-esteem. After operating like that, is when you get a totally clean coin and the right privacy.
