I have been using bitcoin successfully, and NO issues...Recently a friend of mine that it is not safe because it can be tracked. My friend
said that I should use MXR instead. Someone please provide some clarification. If I should convert to XMR or isthis guy exaggerating?!?
What do you really need from this community because from the look of things what you are talking about are two different thing's if you talk about security, you can have 100% security with Bitcoin it all depends on how you treat your Bitcoin, and even MRX have it own vulnerabilities it all depends on how you treat your coins.
Your friend could have been traced and tracked through many means apart from bitcoin as a matter of fact, having bitcoin is not the reason or means that your friend is tracked, it courbet from his details or devices so let it not sound as if Bitcoin security is not guaranteed.
