Only when your hive power is working do you benefit from it. If you are not active every day, you will lose more and more voting weight compared to users who are active every day. Therefore I can recommend with good conscience to delegate your HP to @xiguang. The APR is currently 8% and I'm sure you can expand the service so that you can profit even more as a delegator in the future.
Try it out and let me know what you think of this great service.
