Ok, so if I dont mind waiting a little bit of time, I could make the fees low to save money?
Yes, you can. Your fee could confirm even if its extremely low but I would recommend to use at least 0.0002BTC/KB. You can set it in Tools>Preferences and uncheck use dynamic fee and set the max fee to be at 0.0002BTC/KB. At the send page, you have to ensure that the "Replaceable" box is checked. Once you've sent, PM me the TXID and I'll see if I can accelerate it.
