I have been mining with Norton for about 5 days now. The wallet shows total assets of $5.79. The dollar amount is higher than the network transaction fee, but the withdraw button is grayed out. I do not understand why this is not working. I have a coinbase account. I understand that it is not worth withdrawing the money now because of the fees. I just need to understand why the button is not working.
The withdrawal button will be active once you more funds than the current fee. As you correctly stated until you have accumulated more it doesn't make much sense to move to coinbase. i will also point out there is no difference with you ETH sitting in the Norton Crypto wallet vs. the Coinbase wallet. The only difference is in Coinbase you can transfer to other currencies including other crypto.
I've asked this thread be moved to the Norton Crypto board where Crypto users will see it.
