Well that 6% is still a lot more than what banks do give you as interest. I don't know the engines of Hive good enough to know what would be better. To keep it at 15% or lower it to 6%.
I don't think that this would matter a lot to the outside world. I don't think that a lot of people did come to Hive to have the 15% interest on HBD. So, I don't think that lowering that would decrease that selling point of Hive, if it is a selling point at all.
