That is a lot of conditions are you asking to get fulfilled and I can kind of help but not exactly. As far as I know there is no coin like that currently on the market but there are a few coins working towards attaining those features. RaiBlocks is going to be adding a layer of privacy in the coming months I have read about it on their ANN page that will be a step closer to what you wish. Also there is a fork of the RaiBlocks code and a new coin called Stone is looking to have essentially all the features you listed there.
