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?!?
Bitcoin has both security and privacy, though the use of mixers are for privacy but banned already form this forum, however, bitcoin itself provides with enough ways whereby you could achieve your privacy once you know how to do that, some make use of secured software client like bitcoincore for some related purpose, while we could as well make use of the layer two network protocols for this or running a full node if we don't mind.
