In order to get the maximum amount of activity points possible, you just need to post once per day on average. Skipping days is OK as long as you maintain the average.

到底有多长的路，如果一个大型研究机构要攻破一个地址也几乎不可能，那样才能让人放心啊

能从比特币地址计算出相配对的私匙么？ 不可能。比特币地址原理是基于EDSA即椭圆曲线加密算法的，由该算法可以有私匙算出公匙，但是不能由公匙反向计算出私匙。具体原理请点 这里。 |

要是在能看到的将来就能暴力破解的话，我想没有这么多人（其中还有好多密码高手）玩这玩意儿了

不是算出來的, 根本沒有人有這地址的private key. 如果可以算出這個來, 等於是把bitcoin破解了 另外最後那6位是檢查碼, 不能改變的 |

也不一定是他设定了前面这么多位，碰巧出现也是有可能的。 比如他设定的时候是7个“1”开头的（这是短时间内可以算出的），刚好算出来的时候后面跟了更多的“1”，可能碰巧而已。 |

这是一个无效的地址，发到这个地址的币就相当于被销毁了。
