Buy cryptos with prepaid credit card (Visa / Mastercard)

Hi!

Nowadays, it can be very difficult to buy cryptos anonymously (without KYC), especially if you want to buy on a regular basis.

I know No-KYC exchanges exist. But if you have to pay with your own credit card, your anonymity is greatly reduced.

But what does prevent me from buying a prepaid credit card (Visa or Mastercard) on a local shop and then using it on some websites such Changelly?

Thanks!
