From Circle’s IPO to Tether’s Dominance: How Stablecoins Ignited a Modern Financial War for Dollar Supremacy

Introduction: A Financial Revolution That Will Define the Future

In June 2025, a company named Circle went public on the NYSE. Its stock price skyrocketed sevenfold in a week, making it the hottest “magic stock” on Wall Street. However, the market’s intense focus wasn’t just on its soaring valuation, but on what its business model represented: a potential subversion of the global monetary system. Circle’s core business is deceptively simple: you give me $1 in cash, and I give you a digital token called USDC, with a promise to exchange it back 1:1 at any time. This straightforward “exchange” business supports a market capitalization of nearly $50 billion and has thrust the concept of “stablecoins” onto the center stage of global finance.

From coffee shops in Argentina accepting USDT payments to Vietnamese fruit exporters settling transactions in crypto, stablecoins are penetrating the global economy at an unprecedented rate. In 2024, their transaction volume surpassed that of Visa and Mastercard for the first time, with a total market value exceeding $200 billion. This is more than a technological innovation; it’s a modern financial war centered around the hegemony of the US dollar. In this war, who are the rule-makers, and who are the rebellious challengers?

The Clash of Titans: The “Good Student” of Compliance vs. The “Problem Child” of the Wild West

The stablecoin market is currently dominated by two giants, representing two starkly different paths of development and vividly illustrating the tension between regulation and freedom.

Circle (USDC): The “Good Student” Embracing Regulation

Founded in 2013 by serial entrepreneur Jeremy Allaire, Circle initially aimed to be the “PayPal of Bitcoin.” However, the team quickly realized that Bitcoin’s extreme price volatility made it unsuitable for everyday payments. In 2018, Circle made a pivotal strategic shift, partnering with Coinbase to launch USDC, a stablecoin pegged 1:1 to the US dollar.

Circle’s business model is akin to a “digital-era super bank.” Users buy 1 USDC with 1 USD. Circle then invests the received dollars into low-risk, highly liquid assets like short-term U.S. Treasury bonds, earning an annualized return of about 4-5%. Since Circle pays no interest to USDC holders, this is almost a cost-free interest rate spread. In just four years, its revenue exploded from $15.4 million to nearly $1.7 billion, with 99% of it coming from interest on its reserves.

Circle’s secret to success lies in its unwavering compliance-first strategy. It proactively engages with regulators, publishes regular reserve reports audited by third parties, and has the majority of its assets custodied by BlackRock, the world’s largest asset manager. This transparency has earned it the trust of institutional investors and made it the first global stablecoin issuer to comply with both the U.S. Stablecoin Act (GENIUS Act) and the EU’s Markets in Crypto-Assets (MiCA) regulation.

However, this compliance comes at a cost. Circle’s deep integration with Coinbase requires it to pay over 50% of its reserve interest income to Coinbase as “distribution costs,” which is both the cornerstone of its success and a potential risk.

Tether (USDT): The “Problem Genius” on the Edge of the Gray Zone

If Circle is the model student, then Tether is the problematic genius who gets the best grades while constantly testing the boundaries. Tether’s USDT commands over 60% of the global stablecoin market, more than double that of Circle’s USDC.

Tether’s origin story is legendary, co-founded by a former plastic surgeon and a former Disney child star. It is registered in the tax haven of the British Virgin Islands, with a famously opaque ownership structure. Unlike Circle, Tether has never actively sought regulatory approval, choosing instead a path of “wild growth.”

It is precisely this “non-compliant” nature that has given it an irreplaceable position in certain markets. In countries under U.S. financial sanctions like Iran, Venezuela, and Russia, USDT has become a “digital dollar” outside direct U.S. jurisdiction, providing an anonymous channel for cross-border fund transfers. In nations with rampant inflation like Argentina, USDT serves as a “lifeline” for citizens to protect their wealth.

This freedom, however, is mired in controversy. A UN report labeled Tether the “top choice” for money launderers in Southeast Asia, and the transparency of its reserves has long been questioned. Nevertheless, thanks to its first-mover advantage and unparalleled liquidity, the “network effect” has made USDT’s position difficult to challenge. Its immense profitability (its 2023 profits even surpassed BlackRock’s) has also gradually built a “too big to fail” confidence in the market.

Comparison Table: USDC vs. USDT

For a clearer visual comparison, here is a table summarizing the core differences between USDC and USDT:

The Decentralized Utopia: The Experiment of MakerDAO and DAI

Beyond the world of centralized stablecoins, a group of tech idealists is conducting a more radical experiment. They envision a monetary system without banks or corporations, governed entirely by code and community. MakerDAO and its stablecoin, DAI, are the products of this ideal.

DAI is unique because it doesn’t rely on any centralized entity’s dollar reserves. Instead, users mint DAI by “over-collateralizing” crypto assets like Ethereum in a smart contract. For example, by locking up $150 worth of ETH, a user can borrow 100 DAI. This design aims to buffer against the price volatility of the underlying collateral, maintaining DAI’s 1:1 peg to the dollar.

The entire system’s interest rates, liquidation mechanisms, and other parameters are decided by MKR token holders through on-chain voting, creating a form of decentralized “monetary policy.” Although DAI’s market cap is far smaller than that of USDT and USDC, it represents a fundamentally different possibility: a financial system that doesn’t require trust in any human institution.

The New Financial Cold War: Political Alliances and Regulatory Capture

As stablecoins grow in scale, they are inevitably drawn into the vortex of geopolitics. Today, the market has quietly formed three major political factions:

1. The Tether Alliance: Backed by figures like the former U.S. Commerce Secretary, Wall Street giant Cantor Fitzgerald, and SoftBank’s Masayoshi Son. By purchasing massive amounts of U.S. Treasuries through Cantor Fitzgerald, Tether has become the 19th largest holder of U.S. debt, forming a delicate symbiotic relationship with the U.S. financial system.
2. The Circle-Coinbase Consortium: Represents the compliant, U.S.-native force, closely aligned with regulators and favored by Wall Street and Silicon Valley elites.
3. The Trump Family & Abu Dhabi Royal Alliance (USD1): An emerging power, its stablecoin USD1 was used in Abu Dhabi’s investment in Binance, indicating close ties with Middle Eastern capital and the crypto exchange giant.

Meanwhile, the passage of the “GENIUS Act” by the U.S. Congress signals a formal move by regulators to “tame” the stablecoin industry. The act establishes high barriers to entry, requiring full reserves, monthly audits, and AML compliance. This is a major boon for Circle but poses a significant challenge for offshore issuers like Tether.

Interestingly, whether it’s the compliant USDC or the “gray” USDT, both objectively reinforce U.S. dollar hegemony. Every stablecoin transaction is a digital extension of the dollar, silently siphoning global liquidity into the dollar system. This is a modern financial war fought without gunpowder.

The Future Battlefield and Our Tools

In this revolution that is reshaping the global financial order, both institutions and individuals must understand and adapt to the new rules of the game. Stablecoins are not just a technological innovation; they are a core variable in the future of international competition. For users active in the Web3 world—whether engaging in DeFi, trading NFTs, or hunting for opportunities like airdrops—managing multiple on-chain identities and assets has become the norm.

However, operating multiple accounts comes with significant risks, especially from “Sybil attack” detection. Projects and exchanges use browser fingerprints, IP addresses, and other data to identify linked accounts. If detected, all your efforts could be wiped out.

This is where FlashID comes into play. FlashID is a professional antidetect browser that allows you to create multiple, isolated browser environments, each with a unique digital fingerprint. This means you can securely manage your various Web3 wallets, exchange accounts, and social media identities without worrying about being banned due to account linkage.

Furthermore, FlashID’s advanced RPA automation and Window Sync features can dramatically increase the efficiency of multi-account operations. You can automate repetitive tasks (like daily check-ins, batch transfers, or airdrop farming) or perform an action in one window and have it mirrored across all others, saving you immense time and effort.

In the financial revolution led by stablecoins, having the right tools is like having the best equipment on the battlefield. FlashID protects your digital assets and helps you navigate this new continent of opportunity with security and efficiency.
