What was the other BCN
There was no other BCN, it was Bytecoin, but the symbol was BCE (thread link above), and it was abandoned and dead before DStrange was allegedly trying out of the blue to mine it and allegedly stumbled across the new cryptonote Bytecoin BCN.
I don't know the answers to your other questions.
Interesting. Ok so theoretically speaking is it possible Dstrange is telling the truth and stumbled upon BCN...how does he then know the devs and get appointed as PR man? For all we know this is all some fairy tail.
How do we know the entire team is not one guy or just a huge story?
