Its all good using a bitcoin mixer, but they're also an easy way to lose your hard earned cryptocurrencies. One of the popular scams going around are mixers like mycryptomixer.com that are setup to steal large deposits from users. Take the case of mycryptomixer that stole 13 bitcoins, over $600,000. Use a mixer by all means, but do your due diligence first and only trade amounts that you can afford to lose. You can find more of this story here:
