so I need to delegate in the future to the hiver's chosen?
No, a delegation is not a power-up.
When you delegate HP, you still own your HP and you can remove your delegation to get them back.
When you power-up another account, you give them to that account. Consider it as a shortcut to transfer + power-up
I finally found that you can change the name to power up ALWAYS SOMETHING SIMPLE 😂😂😂😂😂 Thank you very much @hivebuzz
