Sure, I agree I should be more specific.

I guess I mean if we're thinking about investing 3000-6000USD, and electricity is a profitable figure, (.1-.15usd/kWh). That's my situation--I had around 6000 to invest and i went half into hodling a coin portfolio and half into a 6 card gpu mining rig. This way I can build value in the more traditional I minable coins like BTC, LTC, etc and also build relatively consistent growth in a bunch more.
Diversified growth caps potential gains for sure, but it definitely can give more sustained returns.
