Upbit has been the main liquidity pool and trading pair for HBD for years.
Things have changed a bit in the last year with the growth of the internal market and the Cubdefi pools on BSC.
Here is the chart for HBD on Upbit in 2022:
The supply has reached an all time low with just around 1.2M HBD. It was around these levels back in July after growing again to 4M HBD at the end of August. Since then the supply has been going down, and recently has dropped further with the overall crypto prices. Just in the last month the supply has went down from 2.6M to 1.2M HBD. Not much left now.
At one point this drop has made a pressure on the HBD price, but it was short leaved.
