I still haven't tried this service out yet, but it may be good for my daughters, as they are getting into Splinterlands, and want as much DEC as they can get to purchase cards and other things in the game.
Getting liquid Hive would allow them purchase more DEC sooner, although I guess now is not the best time to use liquid HIVE to do anything, the value is abysmal at the moment. Hopefully it can get back to 17 or 18 cents soon.
