I have changed the exchange qualifier a few times over the last few months. The current version still leaves stagnant coins on the list for far too long. I am making it so that a coin must be on an exchange within 30 days. It is easy to get on the minor exchanges and if a coin cannot manage that, it is already dead. In addition to that, a coin must still be add to a major exchange within 60 days.
These rule changes will immediately affect several coins. Additionally, I need to go back and check all coins because some may have been de-listed from exchanges.
