Would another war in the middle east affect crypto
Nope. But it might influence a quality for living for everyone. So much more important thing than Bitcoin. Middle east is getting more and more irrelevant with every year that pass. There will be lees and less tension created by superpowers among Middle east neighbours in upcoming years. Tensions will move to South America and mainly Africa.
I do agree with this, the influence that middle East has is diminishing in the world, with the world moving more towards green energy now, what happen in the Middle-East will likely remain regional issue IMO. As for Crypto, if you are talking about Asia, I will say it is going to affect Crypto greatly but not Middle East because not much money is entering the space from that part of the world
