It's just that I'm not seeing a link here. Do you think BTC might have had a role in preventing the Iraq war? What happened during the Vietnam War? What about the Rwanda genocide?
Are we talking about Bitcoin supreme being that's coming down from the sky?
Bitcoin is nothing more than a tool... it can help you if you know how to use it, Bitcoin can help all of us with creating a new monetary system, of course, if we find a way to use it properly! By "we" I think about the entire world...
I never heard "about how BTC will prevent wars", simply people are the only ones who can do it... after all people are starting them! For all sorts of reasons we can say, and most of them are connected with money! Bitcoin can't magically solve the "money problem" in the world, but as a decentralized system, it can be used for creating a new environment, where all the people of the world can have a vote, where the system is truly the same for all... let's say that the current system is rigged, all those wars you mentioned were created by powerful to make more money and resources for themselves, and this system needs to be changed! I think Bitcoin and crypto together can bring a better system, but how will it play out we will see!
