Ok you are an old member of this forum and you have staked your address, so you can recover it in case your account was hacked.
and you also did a KYC from airdrops, bounty campaigns, and various exchanges.
And on all these activities, you'll only use one address
Then one day you woke up and found out you received 10000 Bitcoin
from a wallet coming from one hacker's wallet who just hacked one big exchange..
And so many people know who you are where you are located and your status in life
because you are using only one address...
So what do you think will happen to you now..
This might very fictional but the possibility is there.
What I'm trying to emphasize is to avoid KYC and using only one address.
Yeah pretty unrealistic but hey, who knows. It might happen to anyone. So here is the situation. You use only one address (idk why would you do that) and have gone through all KYC shits, staked your address and what not. So you probably are an honest guy. So, all you would do is return those coins to the proper people/exchange. You don't want to run away with those money since you will get caught anyways. Return it and they might reward you with something. Few coins vs risking jail time? Few coins please.
