Bitcoin is already part of the global system, but the only opponents of this head of state!
Bitcoin is being used at almost every corner of the world but still the number of people who are using bitcoin are not that much and that it will take a lot of time for bitcoin to be globally accepted and that you cannot expect this thing to happen in a day or two. It can only happen once the governments will declare these crypto currencies as legal currencies and that they will start regulating bitcoin.
I think that bitcoin is capable of being a part of globalization in the future if it is accepted in various parts of the world. Because we all know that Globalization is a process of interaction and integration among the people, companies, and governments of different nations, a process driven by international trade and investment and aided by information technology. Yep bitcoin has the interaction but it doesnt has the recognition of all the parties. However I believe that with the development of advanced technology and the necessity of it ,bitcoin will soon become a legal currency and then it can connect all parts of the world without a doubt.
