I would like to ask what is the best way to speed up the confirmation of an unconfirmed transaction. I heard about a website before which you can do it? Anyone?
Thats depend how much fee you included in that transaction.In
viabtc tool its have a minimum 0.0001BTC/KB fee to use their tool.
Or like Lauda said you can rebroadcast your transaction but depends what wallet that you are using.
What wallet are you using? It is likely that your wallet keeps rebroadcasting the TX.
