其他参与者原话Quote from: bytemaster付款一般是预付的，比如一次 1 BTC，连接关闭时退还「找零」。这条规则让单纯的「搜索查询」无法在没有后续交易的情况下完成付费。
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.
一个替代方案是用凑整制。你一次为 1000 个页面、图片、下载或搜索之类付费。用完 1000 页，再买 1000 页。如果你只用 1 页，剩下 999 页可能永远用不上，但这不要紧，因为每 1000 的单价仍然很低。
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.
或者按天付费。你在某天第一次访问该网站时，为 24 小时的访问权付费。
Or you could pay per day. The first time you access the site on a given day, you pay for 24 hours of access.
按 1000 或按天对消费者来说也更容易理解。按次计费让他们担心累积得太快、算不过来。24 小时不限量，他们知道成本是多少。或者如果 1000 次看起来绰绰有余，只要他们觉得 1000 次多于自己会用到的量，就不会担心每点一下都在花钱。
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.
