Hmm, no offense but the unity you are pertaining about sounds impossible for me. Every developer got their own visions for their own coin of cours and each one of them have different intentions — some aim to make a better version of btc, some made it for the sake of business and some just made it for scamming people. On that aspect, unity was already absent.

But you know what, I love the idea of "single existing coin" because what we really want is revolution right? Where all countries across the globe can engage faster and easier way of transaction between one another .
