Is there any way to speed up the stucked transaction by sending more fees?
You can contact Quickseller or macbook-air or some other miners and ask them to help you get that transaction confirmed. They will probably ask for a small payment.
Thank you very much.
You can also try speeding up the confirmations by using CPFP (child pays for parent), and spend the change from the transaction you posted with a higher fee. Not all pools use CPFP though.
Thank you ver much, transaction is confirmed. As I said, I don't have much knowledge about transaction technicalities but I will learn more about it.
Locking this thread as transaction is confirmed now.
