Who cares about the address format? It works right? Why does it matter?
And it's not suddenly, the dev has been talking about the eco-system from the start.
Ok that is true, but then that makes the situation look worse because, if they used another coin's source code while planning to create this 'ground-breaking' ecosystem, something as simple, yet crucially important in cryptocurrency-land, as specifying an address format that could be recognised easily as their own, seems one hell of an omission.
Seriously, anyone with any IT background would recognise that there are ways in which you progress projects and something as fundamentally basic as establishing a unique format for your 'new' coin address is something that you don't just forget to do.
