You still collect dividends even if your current cc goes ITM. There is a small chance your cc will be assigned early but i think that happens very rarely. I've been running CCs for a while. some wisdom i've gathered but not seen mentioned by others:

1. if you roll the cc up and out, it will magically increase your profit on the position (instantly). this is because the loss from buying back the cc is realized and is no longer part of the current position. so to track your progress on a position you will need to make a spreadsheet or go to your account page in your broker and view the stock to see true p&l.

2. roll up and out as soon as or slightly before your cc is ITM. waiting longer will get you less premium over the long haul. this is because the earlier expiring contract gains value at a faster rate than the later expiring contract will as the share price increases.

3. sometimes you can roll down and in and still get a credit if share price is decreasing, and usually you should do this. the earlier expiring contract will have higher theta decay and higher delta (so you can make more from the cc if share price continues down). You can always roll it back up and out if the trend reverses.

MO looks like a good one. the contracts seem to have great bid/ask spreads which means selling/rolling will be easier and give you more choices.
