8 years ago Some examples of bad privacy which can be examples:
This post links to this this transaction which combines lots of coins (coming from a reused address) into one output. We can see this guys cash flow, his earnings over time, it's linked to his reddit account so we know what his business is (selling bitcoin paper wallets) and using closure analysis as in walletexplorer.com we can see roughly how much, when and what he spends his money on (although when he spends to bitpay or another centralized institution, they stop us seeing exactly which goods or services he's buying).
Another example is this post although it has less obvious privacy-ruining potential.
TODO, look up the bitcoin wiki policy on dox and privacy, it may be kinder to blur out people's names/bitcoin addresses/tx hashes.
Not directly related to JoinMarket, but there are a lot of people around here who have thought deeply about using bitcoin privately.
This page really needs updating, most of the understanding is from 2011 https://en.bitcoin.it/wiki/Anonymity
We could also write a new page called something like "how to use bitcoin anonymously" which includes everything.
There is some content here https://www.reddit.com/r/joinmarket/comments/3l4ngt/what_is_the_best_way_to_move_funds_from_one/
People can obtain bitcoin wiki accounts for free by joining #bitcoin-wiki on freenode and asking and waiting.
