Until Bitcoin gets true privacy, I'd say that's a safe start.I am now the proud owner of almost 10K in XVG (verge currency)
I'm thinking to ad some Ripple to that what say you.
I did the math on ripple once. I can't remember how lol but I decided it has a goal around 86 cents or something. It'll probably make a dollar or more but then settle out. Just too much supply. Amazing technology but not a currency per say.
I would only move into real currency applications. In the short term, great techs will make money but I'm mixed on the longterm of investing in the coinage related to things like world computers and blockchain storage tech.
