If you think about it, it might be better to have the Sign-In System be one instead of giving you one free everyday, you get a certain amount of "Sign-Ins" at locations of your own choosing through actions, for example small missions give you 5-10, killing Thanos gives 5000-10000, that kind of thing. So it's sort of like a lottery but you pick the general direction of what's in the pool, and you can save them
