BunsenH is, of course, correct! I had forgotten that the monster bubbles rise at 75% of the monster's max capacity. The point is to get in the habit of collecting on a schedule that keeps production rolling. It isn't possible to really do that for one- and two-element monsters when they reach their cap in a few hours. You do have to sleep sometime, but if you have a high number of three- and four-element monsters, you can still make plenty of coins after the little ones have hit their caps.

For the diamonds, you can save yourself a lot of hassle by waiting until a time that you are regularly available to take a minute or two to collect them for the day. They are critical for advancing in the game, so you should really try to get those miners back to work as soon as the bubbles pop.
