I went through a period of promiscuous speculation before settling on XMR as the best long-term value store and private transmission technology.  I owned anoncoin, darkcoin, boolberry, and maid during that period.  I have not owned any of these for over a year now.  I speculated in ETH for a bit recently, and rolled gains into XMR.  In general I prefer my diversification to be outside of crypto.  All crypto is far too correlated to constitute diversification.  I do scale between BTC and XMR frequently, while market making, however. 

My knowledge of those coins is largely obsolete, so I will make no comments upon them now.
