It all depends on how many cards you have. Its a little complex, but it does require investment to a certain degree. Once you have a lot of cards, then the missions will then start to generate a decent amount of Starbits. But...the price of starbits is low, so the daily return is not so much. Little as a fraction of 1 Hive, up to a few Hive per day, especially those big accounts with many cards.
Thanks for comment bro.
