Mixers are really not needed anymore. If you want to mix your coins, simply register with any exchange, send your coins to them, create a new wallet, and withdraw your coins from the exchange to that wallet. Bam! Your coins are now untraceable.
Unless your exchange knows who you are. Then authorities could pressure the exchange into giving them records of your transactions.
If it's from illegal activity then they can easily track your address and block your transaction or your account in that exchange if they have proof for that. Not safe way to mix your coins but if you are not doing anything bad with your money then exchange will be enough for example it is just came from gbling which other wallet have restrictions and policy for the balance came from gambling site then sending to exchange will be enough to removed the records .
