Hive can become an addictive game. My dad is addicted to Duolingo. It's not a bad thing until you ask him a question while is is trying to gain XP. At the end of the game he gets XP and gems, but those tokens are useless. You can't trade them for anything. All you can do is keep playing the game. At least on Hive I was able to cash in the HBD and pay for my son's braces. One day he will have straight teeth and have Hive to thank for it.
