Politics and economics are inseparable, especially in today's era of globalization, and this has led to concerns about virtual currencies. Namely, about their ability to survive in a nuclear war and nuclear winter.
There is no a clear-cut position on this, just assumptions, which, hopefully, will never become hard facts.
Why Bitcoin can survive
馃挜 Even in the circumstances of a global power outage, Bitcoin would still be able to survive thanks to a distributed network system is uses (there are servers in all corners of the world that maintain the entire Bitcoin network, so destroying the entire network at once is quite an issue).
馃挜 Bitcoins can be received anywhere as long as the device can connect to the satellite Internet downlink and maintain its own power supply (the satellite system already covers most of the world).
馃挜 Electromagnetic pulses released in a nuclear war would not affect the Bitcoin network since it would be frozen in the ledger, waiting to be restarted in the future.
馃挜 If a nuclear war stroke, the banking and monetary systems would be devastated, saying nothing of fiat, which would be significantly devalued by the war. This does not exist for decentralized Bitcoin.
Why Bitcoin will not survive
馃挜 The biggest source of value of Bitcoin is the consensus of Bitcoin market participants, giving BTC its existence value. The higher the consensus, the higher the market value. If the consensus decreases, so does its value. If the consensus dies out, Bitcoin naturally ceases to exist.
馃挜 If a nuclear bomb hits, it would create nuclear dust, which would prevent people from using solar energy, and there would be further shortages of energy as a result. The biggest problem with Bitcoin itself is that it uses a Proof-of-Work consensus mechanism, which consumes the huge amount of energy.
