I was surprised to see Aminorex mention (long ago) that he owned some MAID at Poloniex. Aminorex, do you still own any, or were you just trading it back then? Is it worth spending time to investigate their claims seriously?
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.
