Also, do you know what 60' for a transaction represent as a fee ?
The only "
60" that I can find is the
estimated fee for your transaction to get a confirmation within 60minutes.
It'll be displayed when you click "
Choose..." beside the transaction fee.
And that's part of the "
fee estimation" and wont work unless it's initialized.
Alternatively, you can always use the other option "
Custom". and set your desired fee rate.
The pre-loaded amount is the minimum 1sat/B or 1000sat/kB.
