I am curious to know, how Exchanges treat the stolen money or hack money? Are they really aware of it? Just think, your fund has been hacked and transferred from your wallet to another wallet and then it's deposited to an exchange. If you claim to the exchange about the money, Are they not responsible for taking necessary action? What do you think?
I'm not really sure about how exchanges can handle this situation but In this case, I think the exchange has no right to seize funds of the person who deposited it, because there is no proper proof to ascertain that the funds were hacked from your wallet.
Exchanges has nothing to do with stolen funds at all, they don't have the right to seize the funds without having prior investigation and solid evidences thaf will point directly that the funds are stolen.
Well maybe some exchanges will temporarily lock the account for investigation purpose if you have a solid proof, and it will be more effective if the hacker is KYC approved on the exchange.
Yeah, this is what I'm talking the prior investigation as proper and legal thing to do, freezing an account for suspicious act, this applies on huge amounts hundreds and millions. But KYC on exchanges is not that ideal for their business, KYC implemented exchanges tends to have less number of active users compare to non-KYC exchanges.
