you can buy amazon gift card balances with the dust, use it on your next amazon purchase. thats what i do 🤙
At BTCPrague I noticed https://thebitcoincompany.com/ and tried it out. It's slightly cumbersome as the app has no idea of the giftcard credit card balances but it works sort of. Already paid all kind of stuff with these virtual gift CCs, including ChatGPT, Mercadolibre and DigitalOcean.
A bad thing about these cards is that you always end up with some residual amount that you won't spend ever and after 6 months they expire, leaving you nothing.
The good thing about DO accepting these - in theory - is that I can top up my balance by arbitrary amounts there so I thought I could collect such residues in my DO balance but all attempts to spend close to the card's balance somehow fail.
What do others do to not lose some dollars on each card?
