Almost the entire comments mix "crypto" with Bitcoin or "all cryptos are the same" which is factually false. Please explain how different it is in comparison, the thread is flooded with baseless claims. This is analogous to placing your money under the bed vs. in a bank vault, they're both unsafe technically, but the difference is vast.
Well, I can't speak for why it might be tracable, but can conversely testify that it has dedicated mechanisms for obfuscating and confusing transaction details such as who sent money, who received it, and how much was transferred- mechanisms which are used by default for every transaction, not just for "private" transactions, creating a cloudy swarm of activity in which you can only really tell that "transactions are happening" without access to (or the intense brute-force effort of obtaining) one of the several private keys involved in any given action.
Some ground-laying patents have been filed by CipherTrace, but I think it speaks for itself that the IRS's $625,000.00 bounty on tracing Monero still stands.
