>We don’t know the nature of the next catastrophe, which means we don’t know which preparation is best suited for it. So, keep some flexibility. Keep more mobile assets; have larger buffers, financial and physical; instead of a large house in a nice suburb, perhaps aim for a smaller home coupled with a condo or house in a different jurisdiction? Don’t put all your financial eggs in one portfolio – keep some gold and some bitcoin; keep healthy; update your survivability skills.  The whole article can be summed up with that. Personally, I've done almost all of this. I'm not sure I'm ready to store a significant amount of my assets in bitcoin or any virtual currency due to the following reasons: 1. Dependent on whims of government to allow conversation of Bitcoin to fiat. 2. Tax consequences of conversion. 3. Dependent on internet and complex infrastructure run by hostile corporations. 4. Not tangible, so you don't own them. 5. Few vendors accept anything other than fiat, not easy to trade for products and services. I see all virtual currencies as an inherent risk. They depend on a highly connected list of nodes. Many nodes are required to be connected. We've already witnessed Texas' power grid fail once. Our hostile government/corporations can easily take block chains down by blocking access to the nodes. Most individuals and businesses do not accept virtual currencies so using them isn't practical, in any case. Holding virtual currencies is only reasonable if you can easily convert them to fiat currencies. For now, you can do it. Currently, exchanges require government compliance, therefore you are required to register with positive proof of identity. This removes anonymity so your transactions can be traced from the exchange wallet to the next destination. Once you exchange virtual currencies to fait, there are tax consequences. Since our government is essentially a proxy for corporations, ISPs can easily block virtual currencies by simply blocking endpoints. Banks can extort vendors not to accept virtual currencies by preventing payment of fiat. Since you can't take possession of virtual currencies, you don't actually own anything. If your currency ever changes its algorithm and later you try to use it, you could be out of luck.
