The main argument I heard against it Bytecoin is it being premined, however, there’s no solid proof of that. Therefore it looks like idle talk
The proof is so obvious, so clear, so easy to verify even for a noob that you must be a troll or a sockpuppet account.
Nice try Bytecoin sockpuppet.
If everything was so obvious as you are telling than there wouldn't be any dispute.
http://bytecoiner.org/Bytecoin was launched July 4, 2012.
First time ever we hear about Bytecoin was
March 12, 2014Over 85% was already mined.

...and it is not an official announcement, Bytecoin has never been officially launched**.
Obvious scam is obvious.
EDIT : When I say officially launched, I mean a bitcointalk.org thread with a presentation of the cryptos and its devs.
If you mine it 100% alone, it has no value. If you mine it 85% and then talk about it, it is a ninja-mine.
