I’ve moved significant funds in and out of Marcus and it’s been fine. In fact, one of the reasons Marcus is one of my preferred HYSAs is because funds transferred out seem to appear in my checking out faster than transfers with some other HYSAs.
Also, I like that Marcus allows larger transfers than some others.
