If BTC price rises and we see reward below 50 again then I might delay on the basis that we invariably trade in cycles and so I might as well wait till we are back to full reward once again then use up all WOF at that time.    However right now I see no point to delay, I might get a bigger regard or just the smaller rewards compound daily so might as well take that small accumulating yield more immediately.
  I did by the way get a golden ticket so cant complain, got a few this year though my WOF per day has been rising with the premium benefits so I guess it figures still I did not expect it.    I will stay calm and complacent till I do win the Lambo, expecting a win is bad luck imo :p
