Excuse me, could you please clarify what you mean by "stc pay cost"? Are you referring to the transaction fees associated with using a specific cryptocurrency or payment platform named "STC"? If so, it's important to note that the cost of transactions can vary depending on several factors, such as the current network congestion, the amount being sent, and the specific rules and fees set by the platform or exchange you're using. Additionally, some platforms may offer discounts or promotions that can reduce the cost of transactions.
