Thanks for your replies, I think in general we have the same Idea. My personal bet is, that there will be a run on anonymous crytocurrency in the near future as governments gain more and more controll creating laws and legislations.
I would like to invest a little in anonymous cryptocurrency, but i'm not yet sure which one.

To me my investment should fit 2 main criteria:
1: Good potential for future gains
2: A real secure coin for real anonymous daily use. (i'm not a techie and several coins claim to be anonymous, but i'm unable to judge)

Can you please give me your opinion on which one I should choose and why ? (taking both my criteria into account)

Thanks for your advice !
