You get one dollar worth of advertising if your advertising cost one dollar, yes.  Spent 50 though.  Spent 50 for 1 dollar worth of advertising.

If the **entire** reward pool was $50, those buying and selling these votes have made it worth $1 in reality.  That's a fancy way of driving the true value of this reward pool into the ground, and for what?  19 views on your youtube video?  That's *smart*.
