付款通常会预先支付，比如每次支付 1 BTC，而连接关闭时会退还所有“零钱”。这条规则使得在没有后续交易的情况下为一次简单的“搜索查询”付费变得不可能。
一种替代方案是采用向上取整的系统。比如，你一次为 1000 个页面、图像、下载、搜索或任何其他东西付费。用完这 1000 个页面后，你再为另外 1000 个页面付费。如果你只用了 1 个页面，那么还剩 999 个可能永远不会用，但这没什么大不了的，因为每 1000 个的费用仍然很低。
或者你可以按天付费。在某一天第一次访问网站时，你支付 24 小时的访问费用。
按 1000 个或按天计费，对消费者来说可能也更容易理解。他们会担心按项计费，因为更难判断费用是否会累积得太快。无限使用 24 小时，他们就知道费用是多少。或者，如果 1000 个看起来已经足够多，他们就不会担心每点击一次费用都会增加，因为他们认为 1000 个可能比自己会用到的还多。

Quote from: bytemaster
Payments would generally be advanced, say 1 BTC at a time and when the connection closes any "change" would be returned. This rule makes it impossible to pay for a simple "search query" with no further transactions.
One alternative is to use a round-up system. You pay for, say, 1000 pages or images or downloads or searches or whatever at a time. When you've used up your 1000 pages, you pay for another 1000 pages. If you only use 1 page, then you have 999 left that you may never use, but it's not a big deal because the cost per 1000 is still small.
Or you could pay per day. The first time you access the site on a given day, you pay for 24 hours of access.
Per 1000 or per day may be easier for consumers to get their heads around too. They worry about per item because it's harder to figure if it might add up too fast. Unlimited for 24 hours they know what the cost will be. Or if 1000 seems like plenty, they're not worrying that it's costing more with each click if they figure 1000 is more than they'll probably use.
