USDT as a Tool for Global Surveillance: Why Bitcoin Remains the Only Alternative
With a market capitalization of approximately $186 billion, USDT has firmly established itself as the "digital dollar" for millions of users worldwide. However, few realize that the issuer of this stablecoin holds the exclusive right to freeze funds at any arbitrary address at any time—and actively exercises it. Over the past six months, Tether has blacklisted 2,362 addresses on the Ethereum and TRON networks, blocking assets worth $1.64 billion. Officially, these measures target hackers and scammers, but the very existence of this capability undermines the fundamental principle of non-custodial storage: you control the private keys, but not the tokens.
The "Freeze and Reissue" Mechanism
The architecture of USDT embeds the ability to block at the smart contract level. The functions addBlackList, removeBlackList, and destroyBlackFunds are not bugs but features. Once an address is added to the blacklist, the owner loses the ability to send USDT, and the destroyBlackFunds function permanently burns the tokens. The key point: Tether can immediately issue an equivalent amount at another address. In essence, the issuer can take dollars from one address and reissue them in favor of another. According to BlockSec, there is an average delay of about two days between a freeze order and its execution on the network. The T3 Financial Crime Unit (T3 FCU), established jointly with TRON and TRM Labs, has already frozen over $450 million across 23 jurisdictions since September 2024.
Risks for Ordinary Users
The problem is not limited to targeted actions against criminals. On-chain analytics companies, such as Chainalysis and Elliptic, assign risk scores to wallets. If an address receives a high risk score, AML systems automatically raise the assessment for all wallets associated with it. This means that random users whose coins once passed through a deemed "dirty" address could end up blocked. Moreover, there is no appeals process before the block—you only learn about the restriction after the fact.
Bitcoin as the Only Safeguard
In this context, Bitcoin remains the only major digital asset that does not depend on decisions by an issuer, regulator, or bank. The first cryptocurrency has no administrator, no blacklist functions, and no "big red button" for destroyBlackFunds. Attempts to introduce censorship at the mining level (as with the OFAC-compliant MARA pool in 2021) were firmly rejected by the community. However, it is worth remembering: Bitcoin is not anonymous, but pseudonymous. All transactions are recorded in a public ledger and can be analyzed years later. Breaking on-chain links requires additional tools, such as CoinJoin or specialized mixers on verified coins.
Expert Opinion: Diversifying between USDT and USDC only dilutes dependence on one company but does not solve the problem—the freeze architecture remains unchanged. In a world where stablecoins have become nodes in a global surveillance system, Bitcoin remains the only asset that cannot be frozen, seized, or burned by a third party's decision. This is not just a technical feature—it is a fundamental principle of financial autonomy, which becomes increasingly valuable as cash is phased out.
