The problem with delegating your HP is that it won't leave you much to work with when it comes to Resource Credits to post, comment, and vote etc.

I would suggest using some of your rewards for a while to Power Up your Hive and HBD and then you will have enough to spare to delegate out.

I recommend OCDB... i get a little from them each day for delegating 500HP. Average is about 0.10 Hive per day for that amount of delegated HP.

As far as voting when you are not available to vote manually... you can log into https://hive.vote/ and add accounts that you would vote for anyways and it will autovote for you. You can also find a voting trail to join... but i don't keep up with all of it enough to recommend.

I would say just add accounts you know that post good stuff and add a bunch of them so that way you can be voting automatically all the time. You can adjust it from time to time by changing the weight of the votes and/or removing a few accounts.

For example... i don't post often on my personal account so there wouldn't be much to autovote on. We post an Alien Art Hive curation post 2 to 3 times a week. So, that would be a better option to autovote.

Give the HiveVote thing a try and grow your account a bit and Power Up so that when you do delegate it's actually something that will give you a better return on your resources utilized.

Right now with Hive being down is a great time to buy it with your HBD. When Hive goes back up all that you Power Up will increase your vote and rewards.
