The original Bytecoin has nothing to do with Monero.
Basically the Monero guys noticed that the coin name they originally chose.. was already taken.
It was a mistake i guess because they did not check to see if the coin name was used already.
I believe Bytecoin was a SHA256 coin from many years ago (released before Cryptonote / Monero existed)
Do you see what i mean ?
For example Microsoft tried to use the word "Metro" and after they put the word all over their stuff on the web they got sued by Metro AG. a German company who held the trademark for it.
Microsoft had no choice but to abandon the name (for Modern)
You may want to move this to the Altcoin section and maybe make a new topic asking about the history of Monero.
I have few details on it actually.. other than the juicy tidbits of drama
So Bytecoin did continue on long after Monero was a thing.. see what i mean ?
