BitPay allows merchants to accept Bitcoin by converting it to local currency for a 1% fee, though the timing of these transfers creates risk during rapid price fluctuations.

American Express utilizes specific algorithms to detect stolen cards, such as flagging multiple gas station purchases followed by high-end retail transactions. While the card is reliable for international travel, many smaller merchants refuse to accept it due to transaction fees that range from 3% to 4%. These fees are significantly higher than those charged by Visa or MasterCard.
