It said that the transaction was sucessfully added so i'll check in the next couple hours if there is any updates
Thats strange cuz i just noticed that when i made this transaction my setting in Electrum was on Dynamic fee so electrum should have calculated the right fee at the time i sended it but looks like it didn't :/
I've set it to manual fee now so i can choose everytime if i want a fast confirmation or not.. and i activated the RBF for the next times am i correct ?
Personally, i think that's the wisest thing to do... I don't understand why some community members pushed RBF to be opt-in rather than opt-out, but since it's opt-in, i personally think it's a good idear to always enable RBF... It will solve future problems if you ever add insufficient fees again
(no offence tough, i added to little fees to transactions myself in the past, so it can happen to me to).
About the manual fee: i think it's wise to let electrum propose a fee, and then manually adjust it up or down (depending on the amount of inputs/outputs and the current recommanded fee, but also depending on the fact if i'm sending BTC between two of my own wallets, or if i'm sending BTC to a thirth party... In the first case, i don't mind waiting, so i add a lower fee. In the second case, time is usually of the essence, so i add a bit higher fee)
