how anonymous are bitcoins?

most people think bitcoin is stored somewhere.

on an exchange. in a wallet. on a server in the cloud. this is wrong. satoshi corrected this misunderstanding back in 2009 and most people still havent caught up. "the coins are the private key." not protected by the key. not accessed by the key. the coins ARE the key.

if you print that key on a piece of paper and delete the digital copy.... the paper is the bitcoin. not a representation of it. not a claim to it. it literally is the money. satoshi went further: "if you found a way to verifiably destroy the paper, it would be like destroying the coins." this isnt how we think about money. we think of money as a thing that exists somewhere and we have access to it. bitcoin flips that. the access IS the thing. there is no bitcoin in a vault waiting for you. the ability to move it is the only thing that exists.

when i first understood this in 2011, it rewired how i think about value. at unocoin we held keys for millions of users.... and i always knew the difference between what they had and what true ownership means. this is why the self custody debate matters. when someone else holds your keys, you dont have bitcoin. you have a promise from someone who has bitcoin. completely different asset. satoshi also clarified privacy in a way most people get wrong. bitcoin isnt anonymous.... its pseudonymous. huge difference.

"if you post your bitcoin address on the web, then others can see that you have received bitcoins to that address, and if they know that its yours, then they know you have those bitcoins." privacy isnt automatic. its built into how you use it. new addresses for each transaction. never linking identity to keys. the software was designed to make this possible. but you have to do it.

the coins are the private key. do you hold yours?
