"Us vs them" is always there only difference is platform where this occurs. In past it occurred over spirituality then things changed to physical dominance.. thereafter came money as a form of domination. We're living in age physiological domination.  Look at me me now, trying to conquer you with arguments and hollow logic's. It's always "us vs them", m'dear. How can you deny competing economies existing in world? Apply same to Bitcoin ecosystem and ponder. If ' by together' you mean virtual-currencies then for sure, I'm in.

My concern is- Bitcoin is tradition english and Swadeshi Currency will be English 2.0. Even if new English had marginal improvements over traditional English where is the infrastructure? Where are the vast tomes of literature written in English 2.0? Where are the speakers and writers and scholars of this new language? Where are the libraries and Wikipedias full of English 2.0 articles? How many newspapers are written and conveyed in English 2.0? How many podcasts, videos will disseminated in this new alternative currency matters. That infrastructure wouldn’t exist, and neither therefore, would the users. This is merely the natural, spontaneous consequence of network effect, and it applies to English as a protocol for language just as it applies to Bitcoin as a protocol for money.

I'm still contemplating...

Hail crypto-currencies!
Reject Bitcoin!
