Have you ever taken delivery of a cert? 1) You place order for cert. 2) You pay for generating cert. 3) You take deilvery of cert. 4) You tuck cert, away in safe place. There is no reason at all to ever take a cert out of commission except to slow down the amount of people trading. Usually when there is a call to take delivery of certs there is really bad news coming down the pike, i.e. get out of this one now!
