Regarding linking coins to a seller, doesn't SR's internal tumbler solve this issue? And as for linking bitcoins throughout the chain, if I buy 2 bitcoins in my name from MtGox, for example, and Mt.Gox gives up my name to LE, are you saying that if I send those 2 bitcoins to my Bitcoin Wallet in my PC and then later use 1 bitcoin from my wallet to pay for something, my name is still attached in some way to that last bitcoin?You're right saying that SR's internal tumbler takes care of things from the seller's perspective.As for the buyer, if MtGox were to give up a Bitcoin address you used, they can trace the passage of those coins throughout the network by seeing to which address one was sent. This doesn't mean that every coin has your name on it but in the nature of things you must send coins from the same address to which they were sent in the first instance. So if you were to receive two coins from one address and were to send each one to separate wallets, in theory they could still be traced provided you knew the owner of the original wallet.In practice splitting your funds across several wallets or sending random amounts of money to your own wallets using a new address each time is a good way to make it more difficult to track the passage of your coins throughout the network.The most secure method of anonymity is either to buy your coins for cash (a service which as I mentioned I hope to offer in the near future!) or run your coins through a mixing service like Bitcoinfog which for a commission of around 2-3% you can mix your coins with other people's, making them impossible to trace back to you by analysing the Bitcoin network.V.
