# US-Iran peace talks fuel oil price crash, global market asset revaluation, Tether (USDT) moves from "crypto wallet" to eOn May 21, global financial markets witnessed an asset revaluation. With US President Trump publicly stating that US-Iran negotiations had entered the "final stage," market expectations for the reopening of the Strait of Hormuz and the lifting of energy supply embargoes surged. WTI crude oil futures prices plummeted over 8% on May 20, falling below $100 per barrel, and even briefly dropping below $97 per barrel. Ultimately, the July delivery price of light sweet crude oil futures on the New York Mercantile Exchange closed at $98.26 per barrel, a drop of 5.66%; Brent crude oil futures for July delivery closed at $105.02 per barrel, a drop of 6.26%. The yield on the 10-year US Treasury bond fell to 4.58%, and the oil price crash drove market funds back into technology assets such as semiconductors. The S&P 500 rose 1.1%, the Nasdaq 100 rose 1.7%, and the Philadelphia Semiconductor Index surged 4.5%. On the same day, China's latest Loan Prime Rate (LPR) remained unchanged for the 12th consecutive month, at 3.0% for the one-year term and 3.5% for the five-year term, maintaining a stable macroeconomic monetary policy stance.
## I. Tether for Game Top-ups: Bitrefill Gift Cards Connect Global Game Payment Networks
Among global gamers, using USDT to purchase in-game items and top up has become a mature and widely popular payment method. Bitrefill, a leading global cryptocurrency e-commerce platform, allows users to directly purchase digital gift cards for mainstream games such as Steam, PlayStation, Xbox, and PUBG using USDT. The process is extremely simple: users select the desired amount on the platform, choose USDT payment, complete the transfer via the TRC-20 or BEP-20 network (confirmation time is usually within 1 minute), and the platform instantly sends a gift card redemption code via email. Entering the code in the in-game redemption window completes the account top-up. This model breaks down payment barriers between billions of gamers worldwide and the traditional banking system.
## II. Buying iPhones and iPads with Tether: Gate Card and BitMart Card Form a "Digital Dollar" Consumption Loop
Using USDT to purchase Apple products such as iPhones and iPads has become a highly mature and standardized process. Gate Card directly connects USDT, BTC, ETH, and GT to the Visa global payment network. Users do not need to pre-exchange their crypto assets for fiat currency; the system automatically completes the exchange and settlement at the real-time exchange rate the moment the transaction occurs. It supports convenient payments on devices such as iPhones and Apple Watches, covering over 150 million Visa merchants worldwide. Virtual cards are typically activated within 3 to 5 minutes after approval, and the entire process—application, activation, and use—does not require contact with the traditional banking system.
BitMart Card goes a step further, supporting direct payments in 11+ major cryptocurrencies, connecting to approximately 50 million Visa merchants globally, supporting WeChat and Alipay binding, with a daily spending limit of up to $50,000. The virtual card has no activation fee or annual fee, and is instantly approved after KYC verification. The cashback system offers up to 5.5% (new users), with 4.0% cashback on daily online shopping. Cashback is issued in stablecoins, creating a positive asset cycle of "consumption—cashback—reinvestment."
## III. Buying Teslas with Tether: Crypto Cards Bring Large-Scale Auto Purchases into the "Digital Dollar" Landscape
Purchasing a Tesla worth tens of thousands of dollars with USDT can now be done through a standardized crypto debit card. Gate Card supports transactions at any merchant accepting Visa, including Tesla stores worldwide. The physical card also covers card payments, contactless payments, and ATM withdrawals. The system automatically converts USDT to fiat currency at the moment of the transaction, with merchants receiving fiat currency throughout the process. Compliance and user experience are completely consistent with ordinary credit cards. Daily spending limits are up to $500,000, and annual limits are up to $18 million, providing ample funds for large-scale car purchases.
BitMart Card also supports Visa transactions at Tesla stores, major e-commerce platforms, and offline retail stores. Its virtual card has a daily limit of $10,000, the physical card (plastic card) has a daily limit of $50,000, and the platinum metal card has no daily limit, fully meeting the needs of different car purchase scenarios.
## IV. USDT Purchasing Power Advantage: Stablecoins are Leaping from "Transaction Tools" to New Global Consumption Infrastructure
Tether's purchasing power advantage is essentially the structural efficiency advantage it creates in the global consumer payment process. According to data from Memento Research forwarded by Tether CEO Paolo Ardoino on the X platform, the monthly spending of crypto payment cards has risen to $600 million, a six-fold increase year-on-year, with a cumulative on-chain transaction volume of $7.2 billion, completing 24 million transactions involving 1.36 million wallet addresses. Of these, 62.5% of transactions were settled using Tether (USDT), and approximately 90% were completed through the Visa network. Stablecoins are gradually becoming the underlying infrastructure for consumer payments. As of May 21, the number of independent stablecoin holders worldwide exceeded 172 million, with a total stablecoin supply of $304 billion. USDT's monthly active on-chain users reached 24.8 million, accounting for 68.4% of all stablecoin users.
Tether (USDT) has surpassed 550 million global users. Its core advantage lies in eliminating the numerous frictions of traditional cross-border payments: traditional SWIFT channels require 3 to 5 days for cross-border remittances, incur fees as high as 3% to 7%, and cannot be settled on weekends and holidays. In contrast, USDT, on blockchain networks such as TRC-20, has a transaction confirmation time of less than 1 minute, a transaction fee of only about $1, and operates 24/7. From topping up Bitrefill game gift cards to purchasing iPhones with Apple Pay using Gate Card and BitMart Card, and then to purchasing cars at Tesla stores worldwide using Gate Card and BitMart Card, Tether has extended its consumption footprint from the virtual world to physical goods, digital products, and even high-value durable consumer goods such as automobiles, building a global consumption channel of "digital dollar" that runs parallel to the traditional banking system.
