USDT vs USDC: which is the best stablecoin in Portugal?

The USDT vs USDC comparison has become even more relevant for Portuguese investors following the entry into force of the MiCA regulation in the European Union. Issues related to regulatory compliance, taxation, and availability on European exchanges have begun to influence the choice between these two stablecoins.

In this guide, we analyze the main differences between USDT and USDC, the risks associated with each, and what Portuguese investors should consider before making a decision.

USDT vs USDC: main differences

Although both seek to maintain a 1:1 parity with the US dollar, there are important differences between USDT and USDC.

USDT is issued by Tether and is currently the largest stablecoin on the market in terms of market capitalization and trading volume. Its high liquidity makes it available on virtually all exchanges and trading pairs.

USDC, on the other hand, is issued by Circle and has gained notoriety for adopting an approach more focused on transparency and regulatory compliance.

In general, USDT continues to lead in liquidity and global adoption, while USDC tends to stand out for its transparency and alignment with the regulatory requirements of Western markets.

Main advantages of USDT:

• Higher global liquidity
• Available on virtually all exchanges
• Large number of trading pairs
• Strong presence in international markets

Main advantages of USDC:

• Greater transparency of reserves
• Strong focus on regulatory compliance
• Growing popularity in Europe
• Good integration with institutional platforms

USDT vs USDC: which is safer?

Security is one of the most important factors when choosing a stablecoin. The main goal of a stablecoin is to maintain its parity with the reference currency. To do this, issuers must hold sufficient reserves to support all tokens in circulation.

Tether has faced several controversies over the years related to the composition of its reserves and the disclosure of financial information. Although the company regularly publishes reports on its assets, some investors continue to question the level of transparency provided.

On the other hand, Circle has sought to position USDC as a more transparent stablecoin that is compliant with the regulatory requirements of the United States and the European Union. The company discloses detailed information about the reserves that support USDC and has actively collaborated with regulators.

When evaluating the security of each stablecoin, it is worth considering:

• Transparency of reserves
• Quality of assets supporting the stablecoin
• Track record of the issuing company
• Relationship with regulators and financial authorities

Despite these differences, it is important to remember that no stablecoin is completely risk-free. Factors such as banking issues, regulatory changes, or extreme market events can temporarily affect the stability of any digital asset.

Both USDT and USDC have experienced small deviations from parity throughout their history, but both have managed to recover quickly in normal market situations.

How does MiCA affect USDT and USDC?

The MiCA (Markets in Crypto-Assets) regulation represents one of the biggest changes ever for the cryptocurrency sector in the European Union. The goal of MiCA is to create a common legal framework for companies and digital assets across all Member States, increasing investor protection and promoting greater transparency.

What changes for Portuguese investors?

For Portuguese investors, MiCA has brought greater clarity regarding the use of stablecoins within the European Union. One of the main consequences has been the increased attention given to stablecoins that meet European regulatory requirements. In this context, USDC has often been pointed out as one of the options most aligned with the new rules.

Although USDT continues to be widely used globally, some market participants believe that the European regulatory environment may favor stablecoins that are closer to the requirements defined by MiCA.

With MiCA, Portuguese investors should pay attention to:

• Regulatory requirements applicable to stablecoins
• Changes in the availability of certain assets
• Policies of exchanges operating in Europe
• Greater protection and transparency for users

In practice, investors should follow the evolution of the rules and regularly check which stablecoins are supported by the platforms they use.

What should Portuguese investors consider?

The answer depends on each investor's goals.

Taxation and regulation

In Portugal, stablecoins are generally treated as crypto-assets for tax purposes. Although legislation may evolve over time, investors should consider that operations involving stablecoins may have tax implications, depending on the type of transaction performed and the holding period of the assets. For this reason, it is advisable to keep a detailed record of all operations and monitor any changes in Portuguese legislation.

From a regulatory point of view, USDC seems to benefit from a positioning more aligned with current European Union trends, while USDT continues to stand out for its massive global presence.

Euro-backed vs dollar-backed stablecoins

Another relevant factor for Portuguese investors is the choice between dollar-pegged and euro-pegged stablecoins. USDT and USDC track the value of the US dollar. This means that an investor residing in Portugal is exposed to fluctuations in the EUR/USD exchange rate. When the dollar appreciates against the euro, investors may benefit from this currency appreciation. However, the opposite effect is also possible.

Euro-backed stablecoins can be interesting for those who want to:

• Reduce currency risk
• Maintain direct exposure to the European currency
• Prepare for future expenses in euros
• Simplify day-to-day financial management

Even so, dollar-backed stablecoins continue to dominate the market due to their superior liquidity and greater integration with exchanges and DeFi protocols.

USDT or USDC: which should you choose?

For Portuguese investors, the choice between USDT and USDC depends primarily on the importance attributed to liquidity, transparency, and the regulatory framework. Although both stablecoins are widely used, the evolution of MiCA may make these factors even more relevant in the coming years.

Before investing, consider factors such as your risk profile, financial goals, and exposure to the dollar. As European regulation evolves, keeping track of these changes will become increasingly important.
