它随区块填满逐步抬高手续费要求：
It ramps up the fee requirement as the block fills up:
<50KB 免费
<50KB free
50KB 0.01
50KB 0.01
250KB 0.02
250KB 0.02
333KB 0.03
333KB 0.03
375KB 0.04
375KB 0.04
以此类推。
etc.
这是典型的定价机制。前 50KB 卖完后，价格涨到 0.01。250KB 卖完后，涨到 0.02。到了某个价格，只要你愿意出价比其他客户高，你几乎总能挤进去。
It's a typical pricing mechanism. After the first 50KB sells out, the price is raised to 0.01. After 250KB is sold, it goes up to 0.02. At some price, you can pretty much always get in if you're willing to outbid the other customers.
只附上最低的 0.01 就已经大有帮助。
Just including the minimum 0.01 goes a long way.
