In the next 7 days ION will be at a minimum of $.5 or .00023 BTC and stay there. This prediction is just based on the recent inflation drop and people starting to figure out that currently compared to owning a DASH node owning an ION node is a much better deal and a breeze to setup. Once you factor in everything else happening in the land of Ionomy you'll see that this is me playing it safe.

I'm saying if you don't have enough data to make an informed decision your happy with then don't invest, there's no rush. Gravity is not that far from release and that I think will cover some of your points about a viable business model.
