With US bombing Iran, talks of WW3 seems closer and closer. I am, of course, not wishing for this to happen as nothing good will come out of it. But let us think for a second how will bitcoin be useful to us should WW3 actually happen? First of all, expect chaos. Fiat Currencies would most likely decline. Governments would need to print more money to budget for fighting other countries. This will surely lead to inflation. This is where crypto would come in handy. Bitcoin can be a safe haven for most.
The most important thing is if you live in a country directly affected by the war, surely people would migrate and seek shelter. Bitcoins can be helpful for doing this as you will not be carrying your country's local currency. I am sure now that people would be buying crypto in fear of the war happening.
In a world where banks may crash or currencies can decline in the value quickly, it would be a tremendous benefit to be able to take your dollars with you, digitally and safely across borders. When your country is in the middle of some conflict, you simply cannot carry packages of money or enter your local bank.
Bitcoin is not subject to any borders and censorship and it becomes even more significant in crisis. It is not the solution to all of it but it has the potential to allow people to get away with some financial freedom. With that said I really hope it will never be so. War introduces nothing but damage and pain. And of course, makes sense that people are gazing at Bitcoin as an insurance policy in turbulent times.
