I can only say three words: power-up, power-up and power-up.

I believe in the future, and the future means growing his/her account as much as possible. This SBD price is a good way to do it at a kind of reduced cost. And this is what I do at the moment. Powering-up any single SBD I get.

Of course, one can argue that getting immediate money is also attractive. But this is IMO a way too short-term vision :) The choice is between a '10 dollars now' and a 'maybe 100 dollars later'. Note that the 'maybe' is of course important. I like betting on the long-term future :)

PS: I deliberately ignore the "immediate money in a week" option that you mentioned in your post :)
