Where did he claim claymore was a bytecoin dev?. I think he is referring to the intentional slow_hash crippling
which was left over during the copy paste process and somehow sneaked past the eyes of the collective 'large dev team', during their expansive audit and review of the codebase.. something which is hardly a stretch to say could have been exploited by those that wrote it in the first place (or indeed an independent third party who knew how to read or write code to a basic level)
