What I'm trying to emphasize is to avoid KYC and using only one address.
is there really still people using only one address ever?
creating bitcoin address is so easy, if you just have only one address
then you haven't been practicing pseudonym transactions in cryptocurrency
Yes there are people using one address I have some friends who use only one wallet on all their transactions, airdrop and KYC
This scenario with 10,000 stolen coins is unrealistic, but there is a more likely one when someone sends you a smaller amount of very tainted coins from darknet markets. However, I don't think it immediately means jail for a victim of such attack, they can build a pretty good defense if they can demonstrate that it was a public address known to everyone and that they don't have any illegal goods in their possession.
What is scary though that just like police plants drugs and other illegal objects on people in order to extort them, they can use this trick with coins in a similar way. In fact, this already happened in Ukraine when police was seizing mining equipment while accusing miners of sending money to terrorists, although these charges were never brought to court - the police simply wanted bribes from miners.
That's true, this is one of the reasons why people should not use one dedicated address and avoid doing KYC with one address for all KYC , hackers can mislead the prosecutors by sending tainted coins to your address, so if hackers sent small amounts of tainted coins from say 100 addresses who undergone KYC and the owners of these addresses are scattered on so many locations,
the prosecutors will be busy checking these addresses and verifying each one of them.
