i just did the same, them adding bch to coinbase messed me up
sent 15,000 bitcoins to Bch and coinbase rep said lost , gone
very upsetting
Kindly correct the above statement as I am pretty sure you never meant to say 15000 btc
. May be you would want to say 15000 satoshi or 15k$? I think their should be ideally a way that if it is not sent to correct address it should either not allow itself in first place to send or should return back form the senders address if sent to incorrect address.
