It seems to us that if you don’t understand something, then the X-Men and women can most probably help.  In this case, ‘Quicksilver’ helps to explain what speed is, and shows us why it might be useful.  Although he’s chosen to use a violent and dangerous hostage-type situation, we would say that the exact same thing applies to trading (although hopefully with fewer knives/bullets etc.). Speed is king so get fast, or get smacked in the face by your own fist.

X-Men Quicksilver!
