I did resell those cards back in the days. I need to figure out how many cards that I sold were not redeemed and contacted the people that operated it. Once I hear back, I will let you know.
Thanks a lot for your input !

Please, if you remember some details, can you enlighten us with the loading procedure ?
As a reseller, did you need to "activate" them ?
Do you have a txid linked to a prypto card in some way ?
This can be extremely helpful.
Cause I can already smell fire and hear the pitchforks.
If you did nothing wrong, you have nothing to dare.
We are trying to figure out the total amounts that have "expired" (under Prypto terms)
The highest security code that has been used and that I found is : 10103984
I kept the script running but this is the highest security code that I found and that has a state which is different from "Not activated, not used".
All security numbers above this one gave this output.
