Why BNB works for hosting in Egypt
BNB sits in the exchange wallet many buyers already use, so the transfer is a withdrawal rather than a purchase. In Egypt the alternative is a card billed in dollars against a Egyptian pound (EGP) balance. Most local cards are billed in EGP, so a dollar invoice may carry a foreign-transaction or conversion fee — that part is set by the bank, not by us.
Paying from a wallet takes the bank out of the transaction. The invoice is priced in US dollars, the BNB amount is locked for 15 minutes at the live rate, and the transfer goes straight to the address on the invoice. Nothing to approve, no merchant category to argue about.
