USDT as a tool of global control: why Tether can take your money, but Bitcoin cannot
Why Bitcoin Is the Only Real Alternative
With a market capitalization of about $186 billion, USDT has become the digital dollar for millions of people worldwide. However, few realize that the issuer of this token — the company Tether — has absolute power over your funds. It can freeze assets on any address at any moment, and this capability is used regularly.
In the last six months alone, Tether has blacklisted 2,362 addresses on the Ethereum and TRON networks, blocking $1.64 billion on them. Formally, these measures are aimed at hackers and scammers, but the very existence of the blocking mechanism means that even on a non-custodial wallet, you are not the full owner of your tokens. Together with the team of the Bitcoin mixer Mixer.Money, we are figuring out how this mechanism works, why ordinary users can fall under it, and why holding stablecoins is riskier than holding Bitcoin.
The Ardoino List: How Freezing Works
USDT is a centralized stablecoin, and Tether does not hide this. Company CEO Paolo Ardoino often emphasizes this feature, contrasting it with decentralized projects, and recommends Bitcoin as an alternative. The ability to block an address and forcibly destroy tokens is embedded in Tether's smart contracts on Ethereum (ERC-20), TRON (TRC-20), Solana, and other networks. The functions may be named differently, but the principle is the same:
- Adding to the blacklist (addBlackList): The address owner loses the ability to send USDT. Any transfer is rejected at the contract level. The address remains active for receiving new USDT and working with the network's native coin (ETH, TRX, SOL).
- Removal from the blacklist (removeBlackList): Restores the ability to transfer tokens.
- Destruction of funds (destroyBlackFunds): Irreversibly burns USDT on the blocked address. Recovery is no longer possible.
After burning, Tether can issue an equivalent volume of tokens on another address — for example, to return funds to victims or transfer them under the control of law enforcement. As noted by Mixer.Money, the issuer can take dollars from one address and reissue them in favor of another. According to BlockSec estimates, it takes an average of about two days between the issuance of a blocking order and its execution on the network.
Promissory Note vs. Digital Gold
Behind every blocking is an external request. Tether freezes an address based on a single verified request from law enforcement — without warning the holder or any appeal procedure. The user learns about the restriction after the fact. The T3 Financial Crime Unit (T3 FCU), created in September 2024 jointly with TRON and TRM Labs, had frozen over $450 million across 23 jurisdictions by May 2026. Companies like Chainalysis, Elliptic, and TRM Labs find stablecoins for blocking through on-chain analytics. They assign risk levels to wallets, and if an address receives a high risk score, random users whose coins once passed through a recognized "dirty" address may fall under restrictions.
Analysts also track Bitcoin, but taking it away from the owner without private keys is impossible. USDT and USDC are debt obligations of a centralized issuer. It retains control at the contract level: blocks transfers, burns balances, reissues amounts. The holder manages the private keys but not the token's rules. Bitcoin has no administrator, no blacklist functions, and no "big red button" destroyBlackFunds. There is simply no one to execute such a request. The risk of blocking does not disappear — it shifts to the level of exchanges and exchangers, where accounts can be frozen.
Privacy After Conversion
Converting USDT to Bitcoin removes the risk of freezing at the issuer level but does not eliminate on-chain surveillance. Additional tools are required to hide the link between addresses. CoinJoin, for example, is easily identified by analytical systems and itself increases the risk score. Centralized mixers break the link but require trust in the operator. Bitcoin mixers on verified coins, such as Mixer.Money, do not mix user funds but use clean coins from trusted investors, allowing the direct link between incoming and outgoing transactions to be broken without increasing the risk score.
The Tether Panopticon: The Price of Security
The freezing function helps investigate crimes and return funds to victims. The FATF has called T3 FCU an "invaluable resource for law enforcement agencies." This contributes to growing regulatory trust in the crypto industry. But the system has a downside. USDT remains a centralized asset, and access to funds depends on the issuer's decisions and requests from authorities. In essence, the stablecoin has become a node in a global surveillance system: a private company connected to hundreds of agencies can freeze "digital dollars" anywhere in the world.
The USDT ecosystem resembles a digital panopticon: most users never encounter restrictions but know that such a possibility exists. Diversification among major stablecoins only dilutes dependence on one company, but the freezing architecture itself remains. Bitcoin, on the other hand, has no single center of control, and there is no one to execute a freezing request at the protocol level. It is the only major digital asset that does not depend on decisions by an issuer, regulator, or bank. It cannot be frozen, seized, or burned by a third party's decision, and its issuance rules remain unchanged.
My professional conclusion: The stablecoin market is an illusion of freedom. Until the community realizes that USDT is not a cryptocurrency but a regulated financial instrument, we will watch the boundaries of financial autonomy shrink. Bitcoin remains the only asset that truly protects against arbitrary control, but it requires a responsible approach to privacy.
