Excelsia is Next Generation Blockchain Platform for Decentralized Applications! it is Project Name! Hope we can bring innovation for this industry. we call it as Bitcoin Version X
So it would be like altcoin of the bitcoin like bitcoin classic.
I just don't get it, you've just mentioned excelsia and then Bitcoin version X, what is the difference between them anyway, i might be interested on new project especially on blockchain development, i truly believe that people could develop blockhain technology in order to make something smart or usefull.
