"支付通常是预付的，比如一次 1 BTC，连接关闭时把"找零"退回。这条规则让为一次简单的"搜索查询"付费、而不再有后续交易变得不可能。"
一个替代方案是用凑整系统。你一次支付比如 1000 个页面、图片、下载或搜索的费用。用完这 1000 个，再付下一个 1000 个。即使你只用了 1 个，还剩 999 个可能永远用不上，也没关系，因为每 1000 个的成本仍然很小。
或者按天付费。某天第一次访问网站时，支付 24 小时的访问费。
按 1000 个或按天计费，消费者也更容易理解。他们担心按次计费，是因为难算清会不会越积越多。24 小时无限量他们知道费用是多少。或者如果 1000 个看起来绰绰有余，他们觉得 1000 个肯定够用，就不会担心每次点击都在多花钱。

"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.
