When you speed up your previous transaction (updating the GAS (gwei) ) just to speed up the transaction.
My question is on the transaction fee I paid,
Do I double pay the fees? For the first transaction (initial transaction) and the second one (speed up transaction)
Yes, Ive also noticed this. The speed up process has been deducted too. But Im not sure if the amount is whole. Ive only try it thrice due to slow processing.
But will give you a heads up if Ive tried it again and the fee is deducted in whole cause I didnt normally check it but Im sure there is a deduction cause you process another different transaction.
