中本聪写道： 你知道，我觉得 90 年代对这件事感兴趣的人多得多， 但在十多年基于可信第三方的系统 （Digicash 等）接连失败之后，他们认为这件事已经没有希望。我希望他们能够 看出其中的区别：据我所知，这是我们第一次尝试一种 不以信任为基础的系统。
是的，这正是最先吸引我注意的主要特点。真正的难题 是让人们切实认可比特币的价值，让它们成为 货币。
如果 10 年后我们还没有以某种方式使用 电子货币，我会感到惊讶，因为现在我们已经知道一种实现方法， 它不会在可信第三方打退堂鼓时 不可避免地被弱化。
它可以从奖励积分、 捐赠代币、游戏货币或成人 网站的小额支付等狭窄领域起步。最初，它可以用于工作量证明应用， 为那些几乎可以免费、但还不能完全免费的服务提供支持。
它已经可以用于付费发送电子邮件。发送对话框 可以调整大小，你想输入多长的消息都可以。 连接建立后，消息会直接发送。收件人双击 交易即可查看完整消息。如果某位名人 收到的电子邮件多到读不过来，但仍希望 让粉丝能有办法联系自己，他可以设置比特币， 并在自己的网站上公布 IP 地址。“向我这个 IP 的 优先热线发送 X 个比特币，我会亲自阅读这条消息。”
需要为免费试用增加一些额外工作量证明、 以免免费试用蚕食订阅量的订阅网站，可以对 试用收取比特币。
弄一些留着也许是明智的，以防它流行起来。如果 足够多的人都这么想，这就会成为一种自我实现的 预言。一旦它站稳脚跟，如果你能毫不费力地向 网站支付几美分，就像往自动售货机里投硬币一样方便， 那么它会有非常多的应用。

Yea, that was the primary feature that caught my eye. The real trick will be to get people to actually value the BitCoins so that they become currency.
I would be surprised if 10 years from now we're not using electronic currency in some way, now that we know a way to do it that won't inevitably get dumbed down when the trusted third party gets cold feet.
It could get started in a narrow niche like reward points, donation tokens, currency for a game or micropayments for adult sites. Initially it can be used in proof-of-work applications for services that could almost be free but not quite.
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."
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.
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.
