As a newbie I made a mistake whilst transferring btc to from Binance and Coinbase. My mistake was I didn't check the receive address with Coinbase and it defaults to eth and I wanted to send btc to btc. So anyway .. I accepted the transfer of btc to eth erc20 and now the funds are lost in eth heaven .. both Binance and Coinbase say they can't help me but I don't believe that. There must be a solution to this problem where I can get my funds either restored or forwarded. Any advise ??
