This is one of the best explanations of the rewards pool that I've encountered.

I believe they raised the hair cut to 30%.

Personally, I think that HBD interest should be considered a major drain on the reward pool.

We had been paying over $100,000 a month in interest on the staked HBD. That is about 1.5 million virtual HIVE. People have been converting over $100,000 virtual hive into hive.

The HBD interest gets dumped on the market in down cycles which puts a downward pressure on the price of HIVE

The rewards pool pays people for curating and producing content. The HBD interest doesn't really do anything for the ecosystem.
