你知道，我觉得 90 年代对这件事感兴趣的人要多得多，但在基于可信第三方的系统（Digicash 等）失败了十多年之后，他们把这看成了一件没有希望的事。我希望他们能看出区别：据我所知，这是我们第一次尝试不以信任为基础的系统。
是的，这是最先吸引我注意的主要特点。真正的难题是让人们实际认可比特币的价值，使它成为货币。
既然现在我们已经知道了一种实现方式，不会因为可信第三方打退堂鼓就不可避免地被削弱，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。
它可以从奖励积分、捐赠代币、游戏货币或成人网站小额支付这样的狭窄领域开始。最初，它可以用于那些几乎免费但又不完全免费的服务的工作量证明应用。
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。连接建立时，消息会直接发送。收件人双击交易即可看到完整消息。如果某位名人收到的邮件多到读不完，但仍然想让粉丝有办法联系自己，他可以设置好比特币，并在自己的网站上公布 IP 地址。“向这个 IP 上的我的优先热线发送 X 个比特币，我会亲自阅读消息。”
需要为免费试用增加一些工作量证明、以免试用蚕食订阅的订阅网站，可以对试用收取比特币。
为了以防它流行起来，现在弄一些可能是有意义的。如果足够多人这样想，就会变成自我实现的预言。一旦完成启动，如果你能像把硬币投入自动售货机一样轻松地向网站支付几美分，就会有非常多的应用。

You know, I think there were a lot more people interested in the 90's, but after more than a decade of failed Trusted Third Party based systems (Digicash, etc), they see it as a lost cause. I hope they can make the distinction that this is the first time I know of that we're trying a non-trust-based system.
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.
