I wanted to buy something on Amazon, but I only had crypto.
So I had Amazon credit I wanted to use, but only had crypto liquid at the time. Didn't want to sell on an exchange, deal with fees, wait for a bank transfer, etc. Just wanted to buy a thing.
After poking around, I found that ACEB sells Amazon gift cards (US, UK, Germany, Canada) paid directly in crypto. No account needed, no KYC, code delivered to email. Bought the gift card, redeemed it on Amazon instantly, and it was done in maybe 10 minutes total.
The "how do I actually spend crypto without an exchange" question comes up constantly, and the answer isn't complicated - gift card platforms exist specifically for this.
No fees beyond the card's face value, no linking bank accounts, no explaining to your bank why you're withdrawing from Coinbase again.
If you've got crypto sitting around and have been waiting for a practical use case that isn't speculation, this is probably the most boring and useful one.
