Hi, TryNinja, Thank you for your reply. I created a new wallet with new addresses and now the transfer from Coinbase is stuck in 'pending' mode. The Electrum address seems to be valid: 1AMpKXkRsYvmfED1gkckj488gmSyFLbmnc
Coinbase usually deducts a fee first, but this time it got into the 'Sent' file without a fee, so I just sent more funds to cover it. This transaction has been sitting in 'pending' for 10 days.
When I am checking on the blockchain there is no transaction id. Not sure if Coinbase is holding it or it is not moving because there is no fee included. Do you think it will end up back in my Coinbase wallet? Or maybe an Electrum wallet is too suspicious to them?
