Here the transaction fee paid is very low .
And no doubt that in the current time we need to pay high fee to confirm .
Today in the night 2:30 AM I got payment from the signature camapagin but the payment not get confirmed yet , the fee is 25sat per byte .
Here I will suggest you to wait for the week if the the payment got confirmed then enjoy if not get confirm then use the bitcoin accelerater as given in the above suggestion post .
If you want another accelerater for your transaction confirmation then I will suggest you to go at mysellium and import your adress and made the fee ( usually they will ask for 0.003+BTC) bump option use .
