It's not a bad thing to delegate SOME of your HivePower to the projects that are doing a good job and you want to support... But, if you give up ALL your HivePower, you are giving your freedom out and relying on someone's "goodwill" to support you... Without having a stake to support others...

It can be "profitable" in the short run (people delegating HP to a project that will upvote their post 100% if they shill them), but in the long term, it harms your reputation, integrity, and the whole platform...
