Why USDT works for hosting in Saudi Arabia
USDT holds its dollar value, so the invoice never drifts between the quote and the transfer. In Saudi Arabia the alternative is a card billed in dollars against a Saudi riyal (SAR) balance. Most local cards are billed in SAR, 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 USDT 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.
