当你不得不逃离家园时如何保证你的比特币安全

从政治和经济角度来看，世界正变得越来越不稳定。世界各地的许多人目前生活在生计和福祉面临严重风险的地方，从极权主义和迫害性政府到总体经济状况严重恶化，他们的生存能力受到质疑。

这使人们处于可怕的境地，他们必须做出选择：是继续努力渡过难关并保住自己的财产，还是留下大部分财产逃离滥用权力的政府或被破坏的经济。如果他们足够幸运，甚至有足够的经济和实际能力首先离开。你不能随身携带大量现金或黄金，它们会在边境被没收。银行账户余额可以被完全限制，这意味着即使在大多数情况下您可以在技术上在全球范围内访问它，它也可以立即被锁定。

你不能带你的房子，你不能带你的车，除非你能开车去你要去的地方（如果你甚至拥有一辆），你不能带任何相当大的实物资产。您能随身携带的就是可以背在背上或装在几个包里的东西。比特币彻底改变了这种动态。它是一种可以将您储存的任何数量的财富跨境运输的交通工具。

所需要的只是您以一种或另一种形式携带十二个单词跨越边境。如果您发现自己的情况已经很糟糕，您别无选择，只能逃离，那么这就是带上您的财富所需的一切。这些是一些最好的选择。

边框钱包

Border Wallets 是一个非常有趣的方案，它利用了人们的大脑与视觉记忆的工作方式。这些工具提供了一种生成所有可能的种子词的二维网格的方法。这可以通过几种不同的方式生成，但我建议任何使用此工具的人都使用确定性生成机制。这确保了在最坏的情况下，如果您丢失了种子词网格的副本，您可以在必要时重新生成相同的副本。

This grid can then be filled in using a recognizable or memorable pattern. Human beings are very visual animals, and the reality of how our minds work is that visual patterns are much easier for the average person to memorize than words. After generating the grid, users can select words on the grid in a recognizable pattern that is easy to recognize. It is critically important to remember the order you are going to follow for actually turning this into a seed phrase. I.e. are you following all the highlighted words left to right in a row, then moving down each row? Are you going down each column top to bottom, then moving to the right one column?

Recognizable shapes are great, a circle, a square, even a Bitcoin B. With the ability to regenerate the same grid, an easily recognizable pattern you can fill in, and the order in which to turn those highlighted words into a seed phrase, Border Wallets present a powerful tool designed specifically to ease the mental load of keeping a seed phrase memorized.

This should allow you to cross an international border without anything identifiable at all that is related to Bitcoin. Just remember, before actually making the trip, test things. Run through the process of creating the word grid, make sure that you can properly regenerate the same grid. Create a test pattern and set it aside, then come back and make sure the pattern you remember arrives at the same word seed.

Once you’ve run through the testing and verified you can regenerate everything properly, you can make the trip out of the country with confidence that your Bitcoin is safe and will be accessible when you arrive at your destination.

Samourai Wallet

Samourai Wallet in addition to their coinjoin implementation Whirlpool, and other privacy features, has one particular feature that has existed from almost the beginning of the project in one form or another: Stealth Mode. This is an incredibly valuable feature in a situation where you must cross an international border.

The mobile application can be set to obscure everything about the fact that it is a Bitcoin wallet. The logo is changed to masquerade as a number of different applications, and all signs of Samourai Wallet being installed are obscured. It can function as either a calculator app, a VPN app, a QR scanner, or a notepad. Each fake application is functional, and when launched has the appearance of being whatever decoy app the user selects. Each decoy app has a different mechanism hidden in it to actually open Samourai Wallet to access your Bitcoin.

It is important to note that this will not stand up to any forensic analysis of your device. I.e. if it is seized and actually inspected using computer forensics software, they will be able to suss out the fact that a Bitcoin wallet is installed. However, a manual inspection of your device (which is much more common if any inspection takes place at all) should give no sign whatsoever to a customs agent that a Bitcoin wallet is installed on your device.

Steganography

Steganography is the technique of hiding a piece of data or information inside of some other piece of information. A good example of this is hiding information inside of a jpeg. It is possible using different digital tools to take a secret piece of information, such as a text document, or a bitcoin seed phrase, and embed it inside of a jpeg. The jpeg would look completely normal, with no changes to the visual image, but the file itself would have the secret information included within it to be extracted by anyone who knew it was there.

Now this requires putting your seed phrase on a computer to encode and embed it, and requires using tools that are not very user friendly (there are web based tools for this kind of thing, but NEVER use something like that to handle your seed phrase or private keys). However, the general concept is something that can be useful.

Do you have a book? Any book? If you do, see if you can go through it page by page and find the words in a seed phrase you have generated in the correct order through the pages of the book. If you can, you’ve just found something that can be used to transport your seed phrase safely without anyone suspecting it. Simply go through the book and highlight (in order) the words making up your seed phrase as you find them. Done.

You can simply stroll through border control with a completely innocuous looking book, knowing that hidden within it is your bitcoin savings.

Memorization

I mention this last specifically because all the other options presented above are much safer for most people, especially given that Border Wallets is a system set up specifically to aid peoples’ ability to memorize their seed phrase in a safer way. In the event that for some reason that is not an option, just memorizing your seed phrase as it is can be a path to take.

But I must stress that this is very risky for many people. If you go this route, be very careful. Test yourself numerous times, memorize your phrase and give yourself a week of not looking at it. Repeat it to yourself in your head every day. At the end of this period write down what you remember and compare it to the original copy. Do this a few times.

到了离开的时候，

最后的想法

上面列出的用于跨越国际边境传输助记词的工具绝非详尽无遗。实现这一目标的方法有许多其他选择，所有这些都在丢失或被发现的风险方面都有自己的权衡。我相信，如果你们中的许多人认真阅读本文，你们一定可以想出自己的方法来做到这一点。

选择这里的选项是因为可靠性、简单性和防丢失的安全性。如果您觉得需要或渴望冒险采用更复杂或自行创建的方式来运输种子，我建议您

在这样做时

牢记这些工具，有一天它们可能会在你从一贫如洗的地方重新开始，还是在你积累的财富完好无损的地方重新开始之间发挥重要作用。
