I am going to be sending 0.0069 bitcoin from my electrum wallet to dnm to place an order and was wondering if anybody would know what fee im going to be paying? i cant seem to work it out for the life of me but want to before i start sending as might not have enough for the actual product.
Electrum does not subtract the fee from the amount you are sending... it ADDS the fee. So, if you need to send 0.0069 BTC, you enter 0.0069 in the "Amount" box and any transaction fee that you enter (or select with the slider) will be added to that amount and then the total of "Amount+Fee" will be subtracted from your wallet balance when the transaction is broadcast.
If you don't have enough wallet balance to cover both the entered amount AND the fee selected... Electrum will give you an "insufficient funds" warning.
