USDT as a Tool for Global Surveillance: Why Bitcoin Remains the Only Real Alternative
With a market capitalization approaching $186 billion, USDT has firmly established itself as the digital dollar for millions of users worldwide. However, few realize that every holder of this stablecoin essentially owns not an asset, but a promissory note that the issuer can cancel at any moment. And Tether is actively exercising this right.
In just the last six months, the company has blacklisted 2,362 addresses on the Ethereum and TRON networks, freezing $1.64 billion on them. Officially, this is to combat hackers and scammers. But the freezing mechanism itself calls into question the very concept of non-custodial storage: even if you have the private keys, you do not fully control your USDT.
The Freezing Mechanism: How It Works
The ability to freeze is embedded in Tether's smart contracts on all supported networks. The process involves three key functions: adding to the blacklist (addBlackList), which prohibits sending tokens; removing from the list (removeBlackList); and, most importantly, destroying funds (destroyBlackFunds). After burning tokens at a blocked address, Tether can reissue an equivalent amount on another wallet — for example, to return funds to victims or transfer them under law enforcement control.
According to BlockSec analysts, it takes an average of about two days between issuing a freeze order and its actual execution on the network. The T3 Financial Crime Unit (T3 FCU), created by Tether in partnership with TRON and TRM Labs, can freeze funds within 24 hours. Since September 2024, this alliance has frozen over $450 million across 23 jurisdictions.
Risks for Ordinary Users
The problem is that not only malicious actors can fall under restrictions. On-chain analytics companies like Chainalysis and Elliptic assign risk scores to wallets and link them together. If your address ever received coins from a "dirty" wallet, AML systems may increase your risk score as well. Ordinary users have already faced freezes due to such indirect connections.
Analysts also track Bitcoin, but it cannot be taken from its owner without the private keys. The first cryptocurrency has no administrator, no blacklist functions, and no "big red button" called destroyBlackFunds. There is simply no one to execute such a request. The risk of freezing shifts to the level of exchanges and exchangers, but at the protocol level, Bitcoin remains immune to censorship.
Privacy After Conversion
Converting USDT to Bitcoin removes the risk of freezing at the issuer level but does not eliminate on-chain surveillance. The first cryptocurrency is pseudonymous, not anonymous. Various tools exist to break the link between addresses: CoinJoin (which, however, is easily identifiable and itself increases the risk score), centralized mixers (requiring trust in the operator), and solutions based on verified coins, such as Mixer.Money, which do not mix user funds but use clean coins from trusted investors.
Expert Opinion
The USDT ecosystem has turned into a digital panopticon: most users never directly encounter restrictions but know that such a possibility exists. The effectiveness of this mechanism strengthens regulatory trust but simultaneously blurs the boundaries of financial autonomy. Diversifying among major stablecoins only dilutes dependence on one company, but the freezing architecture itself remains. Bitcoin, however, is the only major digital asset that does not depend on decisions made 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 regardless of state inflation policies. In a world where control over finances is becoming increasingly centralized, Bitcoin remains the last bastion of sovereignty.
