# Discounted 'tainted USDT' is not a safe arbitrage opportunity

A completed transfer does not establish the funds' origin or guarantee that an address will remain usable.

Applies to: USDT counterparties · issuer policy and a US enforcement example

'Black U' is a colloquial sales label, not a certification we can verify. These sources do not determine the status of any particular wallet; legal consequences depend on facts and jurisdiction.

## USDT has issuer-level controls

Tether's December 2023 announcement introduced a voluntary freezing policy concerning OFAC-sanctioned addresses. A successful on-chain transfer is therefore different from an issuer guarantee that funds can never be restricted. It is also not evidence that every discounted offer involves illicit funds.

## Traceable funds can face legal action

In June 2025, US authorities announced a seizure and civil forfeiture complaint concerning over $225.3 million in cryptocurrency allegedly connected to investment fraud. The announcement credits blockchain analysis and Tether's assistance. A complaint's allegations must not be presented as a final judgment against an unrelated seller.

## Do not buy a story about 'cleaning' funds

Our takeaway: a seller's 'clean' screenshot or discount is no substitute for a credible counterparty and documented source of funds. Decline offers expressly marketed as criminal proceeds. Preserve transaction records and seek appropriate professional help if funds are disputed; another transfer does not establish legitimacy.
