In the original Satoshi whitepaper, it was recommended that Bitcoin users use a new address for each transaction to avoid the transactions being linked to a common owner.
But in reality, when A buys a bitcoin from B, A sends money to B to B's account in an exchange (or whatever account.) It seems that B can be identified via this dollar transaction by an exchange or the authority?
Yes you are right that these identifications came later. But how can one anonymously handle these dollar exchanges? – 171124 – 2018-06-09T01:40:46.990
@171124 Your best bet is a service like localbitcoins.com or similar. – Willtech – 2018-06-09T02:05:52.417
Just try to understand the mechanism. – 171124 – 2018-06-09T02:27:33.537
