You're approaching this from the assumption that the story of their release date is true. Let us take a look at why we should not approach it from that perspective:
3. In deference to the previous poster's claim, a search of 4chandata.org, 4chanarchive.net, or any other 4chan archive site unsurprisingly reveals no mention of Bytecoin.
It was definitely an onion site. I was a network engineer at the time. Just playing around with Tor. I had heard of Bitcoin but was not particularly into crypto at all. The guy I met at the expo was also interested in Tor and during our session he gave me the onion link to the forum thread as an aside, really. At the time Bitcoin was over 10$ and so I thought 'What the hell!' and gave the coin a good run - mining it on my laptop up to around December 2012. Around that time I got a new contract and completely forgot about cryptocurrencies and Bytecoin for a long time after until I hit on Bitcointalk.
Btw - from my time on BCT and ALT - I can see why people get upset easily! Since I started exploring Alts more closely it is easy to see how the conspiracy theorists get a hold. Mainly because if it looks suspicious it usually is!
