When I only started working with crypto, I thought that bitcoin is completely anonymous and it is impossible to track, who is the owner of money. But while I was learning more about Bitcoin technologies, I understood that all addresses can be checked and due to IP address, or your personal information on centralised exchange, you can be found. So privacy is an open question in crypto.
Lets put aside the exchanges, in my opinion (centralized exchanges like Binance) are against the spirit of Bitcoin i.e. decentralization. If IP address is the only way you can be tracked then its not very hard to hide your IP address these days (VPN, OPsec etc.). I don't know the extent by which you can be digitally tracked but there are defiantly ways to hide your digital IDs.
