sell back to the owners for profit

Put it all in the FF7 remake development.

What percentage of PSN accounts are associated with a working CC? I have two PSN accounts and I only use prepaid PSN cards. All my friends also use prepaid cards...

I have 4 or 5 accounts (ones my girlfriend. on was my  nephews and one was a japanese account) only on e was associated with a CC and it expired.

Try to decrypt the encrypted numbers :)

I'd sell 1 million credit card data for a Botnet which takes a random address from the pool, registers with that adress at amazon, and buys with another credit card data several stuff like sextoys, sending them to another random adress from the pool... 76 million times :)

I would actually try and get them first as there is no evidence of them being taken...

If, for some reason, I had stolen them, I'd sell them. I guess that's what's usually done with stolen credit card numbers, and if there's market, it ought to be easy enough to sell them.

77 million weren't stolen. You are assuming every account had a cc linked to it. 

There were no CC numbers stolen yet. Either way though if i did (just for fun), i would make gamefreak make a pokemon MMO
