它已经可以用来做"付费发邮件"了。发送对话框可以调整大小，想写多长都行；一连上网就直接发出去。收件人双击那笔交易就能看到完整消息。如果某个名人收到的邮件多到看不完，但还想让粉丝有个联系上他的渠道，他可以装上比特币，在网站上公布 IP 地址："往这个 IP 的优先热线打 X 个比特币，我亲自读信。"
英文原文
It can already be used for pay-to-send e-mail. The send dialog is resizeable and you can enter as long of a message as you like. It's sent directly when it connects. The recipient doubleclicks on the transaction to see the full message. If someone famous is getting more e-mail than they can read, but would still like to have a way for fans to contact them, they could set up Bitcoin and give out the IP address on their website. "Send X bitcoins to my priority hotline at this IP and I'll read the message personally."
订阅类网站如果想给免费试用加一道工作量证明门槛，避免试用蚕食订阅，可以用比特币来收试用费。
英文原文
Subscription sites that need some extra proof-of-work for their free trial so it doesn't cannibalize subscriptions could charge bitcoins for the trial.
趁还没火起来，先囤一点也不失为明智之举。如果足够多的人都这么想，这就成了自我实现的预言。一旦它启动起来，应用场景数不胜数——如果能像往自动贩卖机投币一样，毫不费力地给网站付几分钱。
英文原文
It might make sense just to get some in case it catches on. If enough people think the same way, that becomes a self fulfilling prophecy. Once it gets bootstrapped, there are so many applications if you could effortlessly pay a few cents to a website as easily as dropping coins in a vending machine.
银行必须被信任，才能让它替我们保管钱、电子转账，但它却把钱一波波贷出去吹大信用泡沫，准备金率低得可怜。我们不得不把隐私托付给它，不得不相信它不会让身份窃贼掏空我们的账户。它们庞大的运营开销，让微支付成为不可能。
英文原文
Banks must be trusted to hold our money and transfer it electronically, but they lend it out in waves of credit bubbles with barely a fraction in reserve. We have to trust them with our privacy, trust them not to let identity thieves drain our accounts. Their massive overhead costs make micropayments impossible.
比特币目前还不适合极小的微支付。比如按次搜索、按页面付费这类场景，没有聚合机制就玩不转；低于 0.01 的支付也不行。尘埃垃圾限额，是首次有意限制这类过小微支付的尝试。
比特币适合的，是比现有支付方式能处理的更小的交易——小到覆盖所谓的微支付上限区间。但它并不声称能处理任意小的微支付。
英文原文
Bitcoin isn't currently practical for very small micropayments. Not for things like pay per search or per page view without an aggregating mechanism, not things needing to pay less than 0.01. The dust spam limit is a first try at intentionally trying to prevent overly small micropayments like that.
Bitcoin is practical for smaller transactions than are practical with existing payment methods. Small enough to include what you might call the top of the micropayment range. But it doesn't claim to be practical for arbitrarily small micropayments.
漏说了微支付的好消息。虽然我不认为比特币现在适合更小的微支付，但随着存储和带宽成本持续下降，它终究会适合。如果比特币大规模流行起来，到那时可能已经不是问题了。另一个让它更实用的办法：我可以实现纯客户端模式，网络节点收缩为数量更少的专业服务器机房。无论你需要多小的微支付，最终都会变得实用。我想，再过 5 到 10 年，带宽和存储都会变得微不足道。
英文原文
Forgot to add the good part about micropayments. While I don't think Bitcoin is practical for smaller micropayments right now, it will eventually be as storage and bandwidth costs continue to fall. If Bitcoin catches on on a big scale, it may already be the case by that time. Another way they can become more practical is if I implement client-only mode and the number of network nodes consolidates into a smaller number of professional server farms. Whatever size micropayments you need will eventually be practical. I think in 5 or 10 years, the bandwidth and storage will seem trivial.
