And how I supposed to buy my morning cigs & coffee ?

just saying.
Well, obviously more mass adoption has to happen
Just like some shops today accept btc... someday they may accept Sling instead!
Shop owners might need or want to go on SlingRoad too, you never know

I think you know how much ....
What has to happen is something like this coin - where there is more actual USE value, and have something the coin is actually used for (the in-wallet market!)
And when all kinds of people start actually USING it everyday then you have real inherent value in the currency (Sling).
Until then it is kind of a crapshoot / speculation.
