Seems like another Cryptonote/Forknote Crap Coin with only 1 part-time dev. A dev, who probably already lost interest in the project.
The fact that the dev has not posted anything here in the last month seems to support that statement.

Besides that, "Sexcoin(SEX)" is an already existing coin, so the name "SXCoin(SEX)" will be a guarantee for confusion.

My conclusion: Crap Coin

I might be drawing conclusions (too) quickly, but obviously the dev is free to react and prove me wrong...
