If world war happens, crypto will collapse because internet will be badly affected, there is only war between 1 or 2 countries then the fiat pouring into crypto will be huge.
I don't think the scenario would be like that because the internet is not controlled by one person...
the world war that is likely to occur in the future will not make the entire world go to war, only a few will war. and maybe the Bitcoin price will go up instead of down because it's been confirmed that there will be many who secure their assets, Who knows.
Every human being always wants peace and only a few people who are ambitious with power who want war, people are fed up with war, people need peace. agree with you the war will not involve many countries but only to the extent that there are internal conflicts in their countries which in the end everyone asks for the involvement of foreign aid which actually worsens the situation.
When it comes to bitcoin it is clear that it has been predicted that next year is the year that bitcoin will contribute a lot to its holders, because bitcoin will continue to increase very well. we are just waiting for the time to see bitcoin increase.
