是真的。用按 IP 发送选项，你就是在把币发给应答那个 IP 的任何人。发送到比特币地址，则没有这个问题。
That's true, with the send-to-IP option, you are sending to whoever answers that IP. Sending to a bitcoin address doesn't have that problem.
计划是实现一个 IP + 比特币地址的组合选项，兼得两者之利。每笔交易仍会用不同的地址，但收款方会用给定的比特币地址，对这个一次性地址签名，以证明它属于预期的收款人。
The plan is to implement an IP + bitcoin address option that would have the benefits of both. It would still use a different address for each transaction, but the receiver would sign the one-time-use address with the given bitcoin address to prove it belongs to the intended receiver.
