Let me use my tool here :)

The debt is almost flat in the last months hovering around 6.5%, even with the price drop of Hive. The speculative HBD from Upbit has been going down, and the HBD there dropped from around 3M to 1.7M now, causing all the HBD supply to go down. It has been balanced out.

In the long run (5+ years), if we don't see HIVE price appreciation, then HBD APR might be an issue. Say we double the amount of HBD in savings, only from interest, and the HIVE price remains same or lower. Then we will have a scenario with 14M HBD in savings, 13% debt if the HIVE price is the same, or higher if its lower.
