Tumbling on bitcoin doesn't work like it used to a few years ago. There are now multiple companies dedicated to blockchain tracking and analysis. All coins coming from tumblers are flagged. It's possible because the bitcoin blockchain is public and every balance and transaction is visible to the whole world.

Many exchanges refuse to accept coins that have passed through a tumbler. If you attempt to deposit these coins, the exchange will refuse to credit you unless you provide copious amounts of documentation. Currently they do not seize your coins but will force you to withdraw them.

Some exchanges are even going through users' deposit histories and are retroactively flagging deposits from coin mixing services: https://twitter.com/kristapsk/status/1374336620158140419

This is why many criminals are moving away from Bitcoin into Monero, which has anonymized transactions and doesn't suffer from the chain analysis problem.

So if someone buys a stick of gum from me after taking rent money from a tainted BTC address, I get flagged?

It only takes a few exchanges refusing to flag coins and the whole flagging system fails.

The bad money gets mixed with the good in the exchanges wallet, and sent to random people...

they may not have a choice if the gov't regulation forces them to flag it.

If tumblers are a problem, why wouldnt monero be? You could view it just as a BTC that has built-in tumbler. I dont really follow this logic of Monero shills. Exchanges can ban both tumblers AND monero.

So can you poison someones wallet if you send them 1 satoshi that’s from a tumbler?
