% {2 c5 ^3 @3 r% ?的确,按操作系统原理来说,智能手机操作系统( iOS, Android )因其原生的“沙盒”设计,所有应用( App ) 都被限制在“沙盒”中运行、跨应用不能访问数据(比如说,微博不能访问微信的数据,反之亦然),因此,其安全性的确要高于桌面操作系统( Windows, Mac OS, Linux )。

NO!
2 ` X: Z3 r! `. v4 U我们仍应加密存储私钥,操作系统是操作系统,应用是应用,操作系统层面提供了额外的保护,并不代表应用就可以不去做自己本应做好的保护共护。事关安全,如下比较方法仍然有效:- e2 u" U3 D; }& w

5 d1 v5 G$ `! H3 m3 a8 C加了密,即便是公交车上扒手机的小偷也懂暴力破解,您仍然能有足够的时间从备份恢复,将比特币转移到新地址上。
5 Z+ u' v8 X: y M: l2 N加了密,把手机接到别人的 USB 线上充个电似乎也没那么可怕了。; E; p3 F+ C4 |
$ D: }8 x/ g! y; a
因此,我们仍应加密保存私钥,就算是像“冷”钱包这样的可以安全的放在家里、物理上保证与黑客隔绝的设备,密码可以简单、不用太长,但有密码还是优于没密码。- J' C# W5 i0 w1 z
否则,万一碰到的入室盗窃的小偷,恰好就懂点比特币呢?有密码至少还能多一道防护,至少还能给您一些缓冲时间来在出现特殊事件时,挽救自己的比特币资产。
