As an analogy you can imagine SACRED tokens are being trickled into a bucket. The SACRED becomes cheaper as the bucket holds more tokens. However, a lot of users redeeming their IC for SACRED will reduce the amount in the bucket, causing the price to increase. As time passes, more SACRED is dripped into the bucket, lowering the price. In a way, it works like an auction where the price of SACRED starts at a higher price and slowly drops until there are takers.
