I only have a single data point on this, but... One friend of mine got a card the same time as me, had the same load/amount pattern, similar disposal pattern, and got shut down after 4 months. When we looked at our transaction differences, the only thing we found was that I used over 50% $500 GC's to load (the rest $100-$200) while he used 80-90% $100 or $200 GC's. Perhaps GB likes fewer load transactions? Or, I am just randomly lucky - either one is possible with GreenDot.

DapperDon - do you load smaller or larger GC's?
