I don't know if you have noticed but the APR of HBD in savings today is 19%.
This means that many of consensus witnesses have decided to lower this parameter within their node. This has made me review my voting list and make sure that everyone I voted for has a minimum of 15% in their APR selection...
Sorry for the rest, I don't understand the criteria by which some witnesses believe that a lower APR of 15% is better than an APR of 20% nowadays, so my decision is to vote only for the witness that give me the highest APR.
I know that I am an "insect" among whales but, at least, I make use of my voting power.
