I'm of the position that the world stands to lose a lot if America imposes war on Iran.
Oil prices will go up and eventually things will become more expensive all around. Gulf countries which produce a lot of the west's oil will be blocked from exporting and a lot of NATO infrastructure in the area including European soil like Souda in Greece and Akrotiri in Cyprus stands to face a lot of instability.
Aside from the hike in oil price, the war also has a negative effect on international shipping. The Strait of Hormuz is a strategic maritime route that connects the Gulf countries to Asia. To avoid being attacked, ships are forced to avoid the strait and to take a longer route, which takes more time and consumes much fuel. As a result, to ship goods between these regions, it now costs more than it should.
Some people say that one of the reasons Iran is being attacked is because they're utilizing their oil to incentivize cheap bitcoin mining, landing their costs to mine a single BTC at around 2k USD. Even if the cost analysis is true it's ridiculous and entire country woold be bombed over this.
The war has nothing to do with Bitcoin mining. The reason for the war is to destroy Iran's capability of obtaining a nuclear weapon. However, we know the US also has other hidden agendas. For example, to control Iran's oil.
