my friend tried to withdraw his ftm to his fantom opera metamask. on the exchange he used the correct fantom opera address but selected the ERC-20 network. is his money gone forever? tried looking for other posts on reddit but all of them seemed to be slightly different circumstances etc. please help my friend is very upset :(
