I do see three different ways for this implementation:
1) Show the coins, even those not matching any Exchange Filter or Exchange Volume settings, but set the Revenue to zero
2) Show the coins, even those not matching any Exchange Filter or Exchange Volume settings, but set the Revenue to zero for the profit switcher and when mining, but show the reported Revenue (although it might be unrealistic) on the Coins tab and indicate it with a gray color
3) Simply hide the coins that doesn't match the Exchange Filter or Exchange Volume settings. It will not be visible on the Coins tab and not possible to select for a mining pool.
Which one would be preferred?
