How are bitcoins tracked?

Question

bitcoin

Hello.
Many times I came across phrases like: "The stolen bitcoins were transferred to the XXXXYYYYZZZZ wallet, they are now watching it."
It is not clear to me how money can be observed if it can be slowly withdrawn from this wallet through mixers.
Maybe I don't understand something?

Answer 2

there are mixers in Zcash / Monero (or only in one of them), there are few of them anywhere else, and certainly not in Bitcoin and others like it (Litecoin, etc.)
they cool it like this: they fire the output and then it went through the whole chain to the original
one through the "mixer or not, what's the difference?

Answer 3

I remember there were stories when the wallet to which bitcoins were "laundered" through a mixer fell due to the volume of the transfer. That is, the volume stood out significantly against the general background and they noticed that N was debited from one wallet, then for some time another wallet received a huge number of transactions totaling ~N
