I believe XMR is the best coin for privacy. I hope to one day see RingCT implemented in the STEEM blockchain Hive account@keiserreport .... you can see it in the roadmap here: https://steem.io/roadmap/confidential/

The STEEM blockchain has the biggest potential to give the most people across the globe an easy tool to keep their wealth safe and private. - not to mention give them a voice / freedom of speech.
