When i used electrum, the fee to send bitcoin was $0.06 or so. I did send bitcoin with no fee and it tooked very long so i stopped doing that.
When i use electrum now, its electrum 2.7.8, whenever i send bitcoin, the fee is $0.25 or so. Is that the default fee now? Is there a reason why the default fee for sending bitcoin with the old electrum was $0.06?
What do you have as the set default for your bitcoin sending fee? 0.0005btc/kb is what it is set to.
Does lowering it mean the transaction will take much lower?
What confuses me is why was the default fee $0.06 with the old electrum and now its higher?
0.0005btc/kb is the default fee. The fee is not fixed and will change depending on the size of your transaction and most transactions won't even reach 1kb.
Lowering the fee will make your transactions take longer. In fact, 0.0005btc/kb is already lower than the recommended fee of 0.0008btc/kb.
I'd recommend you increase the fee according to the recommended amount
here (if it says "80 satoshis/byte" then use 0.0008btc/kb or if 100 satoshi use 0.001btc/kb). Or use the dynamic fee feature.
