Your DVS, once staked starts building up an upvote balance in the background, and a portion of that balance is applied to your next post, so long as your balance is enough to give out an upvote.
Your DHEDGE is a little more complicated. At 10 or more DHEDGE, you start receiving drips, these are dividends paid out in hive, HBD, and various H-E tokens (Just 10 won't yield much). At 100 or more DHEDGE, you unlock thread votes and the !DHEDGE comment command. Thread votes are upvotes on your main leo threads. The !DHEDGE command calls in our token curation accounts to upvote the main post you used the command on. The power of this curation call increases with your DHEDGE balance, as well as the limit on the amount of times called in per day.
