I sold all of liquid Hive that @truthforce had into HBD because I know prices will go down again. What goes up from 1 USD to 3 USD within a few days can also go back down just as quickly.
At one point Steem went up to 7 USD and everyone who had staked SP was screwed out of selling at the top.
I try to always keep most of my Hive liquid for that reason, because now when Hive goes back down we can get more HP for @informationwar.
I see how people use HBD as a trading device, and also to lock in a particular dollar value for savings/holdings. Thanks for the info :)
