My 23 Sat transaction is not getting through for like 20 hours now. I use this fee simply because I know I can increase fee. I wanted to try lower if it gets through easily but not. Now the lowest suggested fee jump up from 40 to 163 @.@
I can imagine using CPFP will be getting a lot more expensive than using 40 Sat at the very beginning =.=
No, SegWit is not related. Just get the PKey and you are good.
I mentioned SegWit because the story involve fee calculation, so SegWit is related.
Oh wow... looking at bitcoin fees now, transaction pool has increased substantially. So it really might take awhile, and low fee really might be starved out :(
