As has been previously stated in other discussions here, and more broadly, a lot (most ?) held Bitcoin has been through a KYC process in it's acquisition, so any on chain activity is by default tied to the legal fiction ID of the holder - apart from that, there is the also the transparent nature of the blockchain, and the default ability to monitor the amounts, activity, and any grouping of other outputs in the sending of transactions (the 'clustering' that Chain analysis companies routinely sift the blockchain to collect) of Bitcoin transacted on chain, unless the user deliberately employs techniques to obfuscate any/some of these aspects - so on chain in particular privacy is weak at best both in relation to ID and to activity using Bitcoin for most people - then there is the potential leaking of location in the broadcasting of a TX unless the user employs other techniques to obfuscate that - it's far from a simple situation, and many people are no doubt revealing far more about themselves and their actions than they would prefer, or perhaps even realise.
