The nightmare dev removed the SDC copyrights for SDC stealth code (what this guy calls "nightsend") and claimed he wrote the code. He only replaced SDC copyright after 100's of posts from people warning of illegal use. The TalkCoin dev was on this forum saying that the nightmare guy stole the code for the wallet from TalkCoin.
Since the "dev" deletes all posts on the matter....here is an explanation of the recent history. Proof listed below.
