All bitcoin and most other cyrptos are trackable, In fact, every bictoin ever mined can be traced threw all wallets it's passed through since the day it was mined, and that going back to 2009. That's not a surprise and has always been known by anyone and everyone with even a basic understanding of how it works.
But it is anonymous, at least unless & until it passes through a wallet with an identifiable owner, such as a a crypto exchange. At that point, the exchange could be contacted and an account owner could be identified via the KYC thing they all do. This is why hacked/stolen crypto is such a problem for hackers to liquidate, and some hacked BTC has sat untouched for years after it's theft because it's digitally tainted.
But for those that want privacy, some cryptos such as ZCash and Monero address this by obfuscating transactions so they cannot be seen or tracked. This level of privacy is both a feature and a liability when it comes to hacking.
