For me globalization and everything to do with it sounds like a new way of controlling minds, kindda when all the globe thinks the same it's easier to rule. and btc is another drop to that ocean of "uniting" tools lol.
It's not a way of controlling minds but there are definitely detractors when it comes to globalization. While there are economic benefits, the impacts it has on the cultures around the world don't really provide a net benefit when you consider all the aspects. Globalization makes it easier to make everyone think the same and it just units labor in a way that makes wages far cheaper than they would be otherwise. It's a net gain for corporations however it's a net loss for anyone who actually works for a living. Regardless of whether Bitcoin is a uniting tool or not (and I doubt it is considering the massive market that surrounds currency exchange), it's only a small segment in an increasingly strange world. I don't think anyone was imagining tech and commerce to advance this fast, and now it's exponentially growing.
Globalization is not a very simple thing to discuss much more implemented across many economies which varies in scale, challenges and threats as well as opportunities. I am for limited globalization and not for unbridled where we don't care what the system can bring to local people. Globalization should be benefiting the people in the first place, otherwise it can just a tool for the powerful to trump on weaker economies. In other words, economies and governments together with the people should be talking and not ignoring each other to sidestep possible blunders that can be hurting the people themselves.
As to what is the role of Bitcoin with globalization and whether it can be positive or negative, this question can be difficult to answer for now maybe we should wait for some years before the full picture can emerge. As of now, Bitcoin is borderless so it can facilitate global eCommerce and this is an important aspect in globalization the seamless flow of money from one country to another faster and with lesser fees. And this is where many people are actually excited.
