I've seen a continuous slide in the value of both my HIVE and alt coins since the decision to raise the interest on HBD to 20%. My HE coins have lost about 80% of their value since the increase in HBD interest rates.

This is a wrong argument, in my opinion. Remember we were in a bear market and the increase of the interest rate in steps, all the way up to 20% was a few months before the bear market began. I would have chosen to protect more of my profits in HBD if I were more inspired too, but I wasn't, lol.
