Dirty crypto is coin whose on-chain history connects it to sanctioned entities, stolen funds, ransomware payments, darknet markets or fraud proceeds. The description attaches to the funds and their trail, not to the token type or the wallet software, and it survives every transfer to a new address. Whoever receives it inherits the explaining.
Dirty coin looks identical to clean coin. There is no marker in a balance, no warning in a wallet app, nothing on the transfer itself. What exists instead is a public trail, and the venue that receives the funds after you reads the same trail you could have read first.
That is where the cost lands. Binance's own help pages describe withdrawals placed under review, with users asked to complete identity verification or a questionnaire before the funds move again (Binance support). Every large venue publishes some version of the same process. Nobody in it is arguing with you about ethics; they are asking for documents, and the funds sit still until the documents arrive.
There is no laundering step that improves your position here. A swap produces a new token, a bridge produces a balance on another chain, a fresh wallet produces a new address — and every one of those steps is itself a public transaction that screening follows. What actually changes your position is being able to show where the coin came from, and having checked before you accepted it.
The result names the category in plain words — darknet market, ransomware, stolen funds, sanctions, scam, mixer — and says whether the funds came to the address straight from the flagged party or through intermediaries. Where the counterparty is attributed, the entity is named rather than described.

No. The swap is a public transaction like any other, and screening follows the funds through it. What changes is the token, not the history behind it.
On chains where a stablecoin issuer holds that authority, yes — Tether's terms reserve the right to freeze tokens and to blacklist token addresses on suspected prohibited use ([Tether legal](https://tether.to/en/legal/)). Bitcoin has no issuer, so nothing freezes on-chain; the venue holding the coin restricts the account instead.
Screen the sending address before the transfer. The check reads the public chain, needs no permission from the sender, and takes seconds in the Telegram bot.

A reviewer looks at the funds that arrived and the path they took, not at every coin you have ever held. Keeping deposits separated by counterparty is what makes that distinction easy to demonstrate.
