Can I take your mind off fear for a moment? The more likely case is that Bitcoin will make it somehow. Perhaps be a freak asset class for some, part of the balance sheet of every central bank, or the foundation for a new society. I hope you also spend time on the case where Bitcoin will leave the USD behind (i.e., be 500k or more). Some people will NGMI when Bitcoin hits 1M USD (see Roger Ver for reference). You certainly don't want to be one of them as this is utterly avoidable. Plan wisely. And yes, it is reasonable for you to spend some time on the case of a sub US$ 1k Bitcoin, albeit it is rather unlikely.
