It's been 4 days now, the exchange has not asked for it and the lucky guy has refused to return the money, not because the exchange has not asked for it, but because he had about 0.275 eth on the exchange and some other altcoins worth about 0.7 eth, in about 1 hour after he received the 24 eth in place of 24 usdt, the exchange emptied all his wallet,
After reading your initial post, the good samaritan side of me kicked in, I would had returned the money assuming I didn't see the other side of the story which comes as a surprise. Thought the exchange was decentralized, how then were they able to seize or empty the account of the user?.
This is why I initially said that the exchange is semi decentralized but claimed to be fully decentralized, any DEX where the user have to deposit ether or token before they can be able to trade it is not fully a DEX, they were able to empty the guy's wallet cus they had full access to the funds that were deposited to their exchange,
I'll be glad if more details are reviewed like the exchange name so we can stay away from patronizing them in the future. They made an honest mistake that they can take to social media and ask for their funds to be returned.
Probably the receiver would see this new development and do the needful, which might benefit him more as the whole world will see his good deed and probably reward him more either directly from the exchange or other source. Although if at last the receiver refuse to send back the fund I won't judge him because if I was in his situation, I'll likely do the same or take back my funds and send back theirs.
Unfortunately, there was no way for them to contact they guy directly cus they had no information of him, the more unfortunate thing is that as soon as the lucky guy discovered they've emptied his wallets on the exchange, he immediately converted about 20 ether to fiat and vowed never to return it even if he was later contacted, I couldn't say much, so he doesn't think am jealous, and beside, if I was in his shoes, I would have done same, I will think about revealing the exchange...
