Hello friend, I currently exchange HBD through P2P because a friend is the mediator.
But before that I have to convert the HBD to USDT for the BSC network. About gift cards, it's a cool and interesting idea, but I don't know how much they are used here in Brazil.
Maybe it has a use, but I don't know how many people do it.
The problem here is the high fees, to have a credit card that accepts Crypto, we have to pass the information to the government and also pay fees beyond the normal use of our card. Honestly, I avoid this.
