It is exactly as you said. As a basic principle, if you don't change anything in your HP, your KE will be 2, which is a very acceptable value. You can use HBD to invest in Splinterlands, other Hive games, or even withdraw it.

The main idea is that, eventually, people will start considering the idea of bringing this resource back and increasing their HP. In more severe cases where KE exceeds 10+, the idea will be to stop providing support until these accounts align with the long-term investment culture.
