Another angle on the Hive side is to buy Hive, power it up with the aim of converting to HBD when (if) Hive appreciates, thus capturing the return in one transaction rather than 15% over the year. I think it is more likely that Hive appreciates by more than 15% in the next 12 months, but of course nobody has a crystal ball.

I don't know what the return on powered up Hive is ,but it's at least a baseline return, but maybe you keep the Hive liquid to better catch shorter spikes ?
