如果 Bitcoin 真发展到非常大的规模，最终也只是让全球 68 亿人分享最多 2100 万个比特币。
Eventually at most only 21 million coins for 6.8 billion people in the world if it really gets huge.
不过不用担心，目前还有 6 位小数没有显示，系统内部总共保留 8 位小数。界面显示 1.00，内部实际记录的是 1.00000000。如果未来出现大规模通缩，软件可以显示更多小数位。
But don't worry, there are another 6 decimal places that aren't shown, for a total of 8 decimal places internally. It shows 1.00 but internally it's 1.00000000. If there's massive deflation in the future, the software could show more decimal places.
如果小数太小、使用起来不方便，我们可以调整小数点的显示位置。钱的总量不变，改变的只是逗号和小数点的位置约定。比如把小数点向右移动 3 位，原来的 1.00000 就会显示成 1,000.00。
If it gets tiresome working with small numbers, we could change where the display shows the decimal point. Same amount of money, just different convention for where the ","'s and "."'s go. e.g. moving the decimal place 3 places would mean if you had 1.00000 before, now it shows it as 1,000.00.
