Just a friendly suggestion, when you broadcast a tx then don't mind to use 1 sat/byte fees for this kind of pool that I will host. Let's save some coin :-P
Can you tell me how can i change the default fee in Electrum wallet and make it 1 Sat/byte ??
Sorry for the question.
It's off topic here.
Click on setting and put tick mark on "Edit Fee Manually".
Then when you will be sending coin, you will see option for edit manual fee on the page. Better you ask anything related Electrum
here.
By the way, 1sat/byte will be huge late since fee is high now.
