- do you have any survival tips during war period?
Well, there is not much to say here because once a war starts, there is nothing to do but have a place to hide to escape death, injuries, and other disasters that will affect you, your family, business, and other useful things that belong to you. So what I mean here is that the only tip you should know and utilise when there is war is to hide. If you do not have the mind to save other people, you should hide yourself, and I think that's just it.
- are there any business that I can do during a period of war so as to sustain my family? Can I still budget, save and earn in Bitcoin?
For the first time you said that during the war you listed things that were affected and you included businesses that were shut down due to the war, so why did you bring business here again? There is no way you are running for your life; you will still be looking for money, especially during the war. When there is war, how can you think about doing business?
However, the only time I think you can do business in this period is when maybe people who were affected immigrate from where the war was booming now have someplace to hide for the main time. Then definitely, you may decide to open even a small store there, and you may get paid using BTC if there are people among them that have bitcoin since they may lack the local currency due to the war.
