Keep in mind that velvet has a similar life cycle as ich, so it will fall off the fish to reproduce which will give the fish a temporary relief. Like MrTusk said, waiting kills the fish. I would really get ALL of the fish into QT for cupramine treatment immediately, be it velvet or ich. Both are killers, just that velvet kills much more quickly.

If you had a fish die in a day or two of showing white spots, it's almost always velvet. Ich doesn't kill that fast most of the time.
