150,000 in HIVE at a price of of 31.5 cents (median price feed) means 476,000 HIVE will be printed. Let's round it up to 500,000.
On another hand, the Huobi HIVE/USDT pair has a daily volume of 15 Million HIVE. Which means that the printed HIVE, assuming they are ALL sold will only represent 3.33% of the daily volume on Huobi HIVE/USDT.
Taking into account the 20 other pairs like HIVE/BTC and HIVE/KRW across multiple exchanges I think we're fine.
Also, a lot of the conversions should be from liquid HIVE that were exchange with HBDs, so probably not all HIVE will be sold.
This is 150k in HBD, so multiply the numbers by 3-4x.
That's what I did 150,000x3 = 450,000 HIVE. I used 500,000.
