Forum:Golden Ladybug and Chain Energy. Heal or no heal?

So, I've been looking around on forums and I can't find anything definitive. On one hand, chain energy's effect says "Each player must pay 500 Life Points per card to Normal Summon, Special Summon, Set or activate cards from his/her respective hand." so it would lead one to believe that activating Golden Ladybug's effect would cost 500LP, but on the other hand, the card tips page for Chain Energy here in the wikia suggests Golden Ladybug as a way of continuous healing, and on a third hand, I read on some other forum that Chain Energy's effect possibly implies "from the hand to the field," which would imply it is a part of the effect specifically for activating spell cards.

But which is it?! I can't find a definitive answer anywhere!
