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 ）。# c3 m9 O; a/ m, U! j- h

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：- `" k Z1 f) X0 R( h

加了密，即使其他人拿到了您的手机，也花不了您的比特币。

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。
