向比特币地址转账时，你不会直接连接收款方，而是像转发其他交易一样，把交易发送到网络。别人无法分辨一笔交易是由你发起的，还是你从其他节点收到后继续广播的。不过目前网络还很小，仍可能有人通过排除法推断出来。等网络扩大后，情况会好很多。
When you send to a bitcoin address, you don't connect to the recipient. You send the transaction to the network the same way you relay transactions. There's no distinction between a transaction you originated and one you received from another node that you're relaying in a broadcast. With a very small network though, someone might still figure it out by process of elimination. It'll be better when the network is larger.
如果按 IP 地址发送，收款方会看到你，因为你需要直接连接对方的 IP。可以用 TOR 隐藏这层信息。
If you send by IP, the recipient sees you because you connect to their IP. You could use TOR to mask that.
如果你不想让别人知道自己正在使用 Bitcoin，也可以使用 TOR。
You could use TOR if you don't want anyone to know you're even using Bitcoin.
Bitcoin 还很新，也没有经过独立的安全分析。如果你很重视隐私，使用 TOR 是一项值得采取的预防措施。
Bitcoin is still very new and has not been independently analysed. If you're serious about privacy, TOR is an advisable precaution.
