I actually only bought these because it was the only way to buy bitcoin with a credit card (I didn't have cash lol) and my plan was to just hold the bitcoin for a month and sell it before the bill came (which I did for a profit). So I redeemed it right away. I was also only a few cities away from where they were being produced so I got it rather quickly

Back then it wasn't a bad way to buy bitcoin. Exchanges and p2p was still so sketchy. I can imagine you weren't the only one to do this. Took me awhile to figure out how to actually buy bitcoin back in the day. Good luck with your sale.
