I'll sell a few HBD's for Hive, and then when the price of Hive goes up, I'll buy a few HBD's back.

This is the way to do it. I don't know what the bottom will be, no one does... but, no one knows the top either :)

Splinterlands assets are pretty good to trade back and forth to increase HIVE btw, as they are linked too. Price in Hive drops, DEC goes up against it. Hive increases, DEC goes down.

Are there any cards that you would like to try? I have some Chaos ones at least as well as some dice that could help and I am willing to delegate you a few :)
