I added som credits to my personal account and hoped I would be able to remove the card that I got registered… but the stripe page doesn’t let me do that.
Also, would you start eating my credits before charging my card if I have both on an organization?
Hi,
A CC is required I’m afraid.

Will defer to people from Fly on the credits-first question.
I was hoping to use the credits as “spending limit” by removing my CC.
It is unlikely, but I don’t like the prospect of having a potentially onbounded charge on my card. 
It is still possible to set charge/transaction limits on the card itself, right?
I suppose but at that point the damage is already done, the cost for 234TB bandwidth doesn’t disappear just because my card refuse to accept it
It does vanish, we credit those bursts back. 
Prepaid credits do get used first!
We don’t have a way to remove a card yet, but that’s something we can do down the road once you’ve added credits. For now, just let us know when you get a shocking bill (we’re betting you won’t).
Good to know, it is not keeping me up at night but I’m rather safe than sorry
