I downloaded Electrum but waiting on GPA to sync so I can verify the public key they have on their site.
I do have a question about "first have to either import or sweep the private key in a non-custodial wallet like Electrum. Then you can send the coins to the Crypto Exchange using current network fees" I now know non-custodial would be a wallet in Electrum compared to Coinbase where they have the keys etc.

I have to run and pick up my kid but I will be back....with more questions. I really appreciate the info everyone. Thank you.
