I accidentally sent 10 ETH from my ETH wallet on Coinbase to an ETC (Ethereum Classic) wallet on yoBit.net back in 2017. This is a common mistake and I know it is possible for the receiving exchange to retrieve the ETH and put it in the correct wallet. The support team on yobit.net has not responded to me in all these years I've been trying to contact them. Is it possible for Coinbase to reverse the transaction given that the Coinbase exchange has the private keys to my ETH wallet from which the ETH was sent? I read somewhere that if I sent it from a private software wallet to which I have the private keys and not an exchange, I would be able to do this. Since Coinbase the private keys to my ETH wallet on Coinbase maybe they can do this. Or is it not technically possible for Coinbase to do it and only possible for YoBit to do it?

Incidents like yours, I also found in my friend. From this experience, I can answer that this is not the fault of Coinbase or any other exchange. And from this experience, caution is very important to us, even though the private key, we hold.
