This is the fee I paid for the transaction. 0.0007164 BTC ( 31.4 sat/byte )
Yes, I can replace my fee.
When I change the value, Electrum gives me a new one, like 41.1 sat/byte. I just confirm but nothing happens. Do I need to change the option to Mempool, ETM (which is set as default) or Static?
I will suggest you to wait, it is likely the mempool will be less congested during the weekend, we are almost in the weekend now. Very possible the transaction fee can be even far lesser than $41 Satoshi/ vbytes. With what I see here, the transaction fee that will make your transaction confirmed in time is high, but the mempool will be decongested during weekend likely, this is just an advise. So far it is your wallet, nothing will happen, only you can cancel or replace the transaction, which means your Bitcoin is safe. But, if you still need your Bitcoin to be gotten confirmed in time, you will need to pay like $8 which can be reduced to like $6 if use segwit, but that is not the main topic now, but wait for the mempool to be decongested rather than paying high fee.
